Omega J8004 Nutrition Center Single-Gear Low Speed Masticating Juicer, White
The Omega J8004 Nutrition Center is a masticating style juicer. Sometimes referred to as a low speed juicer, the Nutrition Center processes at 80rpm, whereas most other juicers process at a speed of 1,650 to 15,000rpm. The low speed protects and maintains healthy enzymes, prevents oxidation and allows juice to be stored up to 72 hours without degradation. The GE Ultem Auger is 8x stronger than most other plastics and the powerful gear reduction is equivalent to a 2HP Motor. The dual stage juice processing system extracts the maximum amount of juice from fruits, vegetables, leafy greens, even wheatgrass! You can also use the nutrition center to turn nuts into nut butters (an all-natural peanut butter), make baby food from natural, fresh ingredients, whip up soy milk, extrude pasta, grind coffee and spices, and mince herbs and garlic. Make delicious and nutritious drinks and snacks that everyone will love. Measuring 7in wide, 15.5in deep and 8.5in tall.

Identical to the J8006, better than the J8005, and a most cost-effective juicer for greens
June 22, 2010

UPDATE: As of March 11, 2013, the J8006 (identical, but with a chrome look), was temporarily $209 on Amazon (sold by Amazon, itself). This had always been a more expensive color. Please be sure to compare and buy strictly on price between these two models. Enjoy!
My wife and I have had this for two months of intense juicing of cabbage and occasionally broccoli. My wife had multiple stomach and duodenal ulcers from medications due to a spinal injury and we combed the internet looking for studies on the best home remedies, as prescription antacids were not healing her. We chanced across two studies on raw cabbage juice healing ulcers in a matter of weeks, so that led me to research juicers.
There are four basic types of juicers. In order of general effectiveness (least effective to most effective) on greens, they are as follows:
1. Spinning blade/centrifugal ($50-$200)
2. Single-gear masticating (like this one) ($200-$350)
3. Double-gear masticating ($425-$550)
4. Hydraulic press w/shredder ($1,000-$2,500)
We were hoping the ulcers would heal quickly and I didn't plan to invest much. In reading the reviews on the spinning blade-type extractors, they seemed a poor choice for leafy greens, but quite good for fruits and other types of vegetables. One additional caveat I found was that juice from such juicers didn't keep that long, apparently due to oxidation and heat friction. My wife grew up with such a juicer and she had always enjoyed it, but she agreed it wouldn't work well for wringing juice from a cabbage.
Next came the single-gear juicers, and these varied from steel to melamine construction to a new high-tech super-hard GE plastic. Steel can oxidize fruit juice and melamine is a soft plastic that is most known for appearing in contaminated animal food from China, which in tests artificially appears as protein. Neither of these sounded good, but in reviewing the latest versions of the J8006/J8004 (they are identical except for the color and $40 difference), I found Omega was using GE Ultem, a plastic at least six times harder than melamine for the augur. This was a huge plus to me.
The double-gear juicers appear to get about 15% more juice out of the same amount of produce, but take quite a bit more time to clean. They are also twice the cost of single-gear juicers. This wasn't worth it to me.
Finally, the hydraulic press juicers get the most juice out, but can cost thousands of dollars. I couldn't find one under $800.
Our Experience:
I decided to get the J8004 and we went to town using it. It's been used probably 40 times so far for about 45 - 60 minutes each time. I make two quarts of cabbage juice at a time and it's refrigerated, with my wife drinking all of it within two days. At the end of the second day, if it's been kept sealed in the refrigerator, the juice tastes virtually identical to when it was juiced (just shake it up a bit because the juice settles).
Directions for the juicer say it shouldn't be used more than 30 minutes at a time. This isn't a problem, as I prepare two plates of cabbage leaves, juice them, turn off the machine, then prepare two more plates of leaves at a time.
The Omega leaves some juice in the pulp, which I now recapture by feeding the mash back through the machine. Strangely, the extra passes go very fast compared with the first one with the leaves, basically because the mash goes in the tube with absolutely no friction, and is much less volume to handle. In general, if you are juicing cabbage leaves, this is how each pass juices out if you got 600 milliliters with the first two platefuls:
1st time - 600 milliliters
2nd time - 150 ml more
3rd time - 50 ml more
4&5th time - 50 ml more total
Yes, the double-gear machines might get more each pass, but I figure that putting cabbage through three times is more than equal to putting the it through twice on a double-gear, and I save $250 for that net of one extra pass.
The unit has held up well and has never stained from all the greens touching it, so save forty dollars and get this over the silver J8006 twin (both units are superior to the J8005 because that unit, strangely numbered higher than this, uses a melamine auger and has only a 10 year warranty). The parts all rinse clean in no time, save for the two filtering portions on the cone the augur presses against. These require a brushing motion (one is included) to clean, and even then the part with the fine mesh retains some cabbage fiber. Fortunately, we put the parts in the dishwasher where anything remaining can be blasted off.
We've used it to mass-grind coffee with an included grinding option. It grinds a pound of coffee in about three minutes.
You can't go wrong with an Omega J8004 if you are juicing greens. We would definitely buy this again, but due to the incredibly long warranty, we don't expect to buy anything for over 15 years!
UPDATE: We've now used it more than 60 days on cabbage and broccoli and used it to make wonderful blueberry sorbet (using the second cone unit for grinding). Putting frozen wild blueberries into it makes a sorbet come out the end that if allowed to thaw, is a perfect cold blueberry juice. This summer we have been using it in this capacity far more than for cabbage. WONDERFUL! (NOTE: My wife's ulcers completely healed by the two month point, so we've moved on to juicing other items.)

The Great Masticator: Omega 8004/8006 perfect for lazy first-time juicers like me

Video review for the Omega 8004 (white version of the 8006) masticating juicer
Likes: Base has a compact 11"x8" footprint, 15-year warranty, quiet operation, ease of juice (har har), 30-second clean-up, efficient, produces a dry pulp, juice is low-foam and fantastic, multi-functional - can be used with included attachments to make nut butters, grind coffee, mince produce, and extrude pasta.
Dislikes: A little slow, narrow 1.5" feed tube, soft/juicy items like cucumbers and citrus fruits need to be pushed down to prevent jamming.
Green juice recipe in the video (sorry I presented some items out-of-frame, I'm a first-time videographer too), produces about 2 cups of juice in 5-6 minutes:
3 stalks celery
6 large romaine leaves
Big handful spinach (2 oz)
Small bunch of fresh herbs (parsley, basil, cilantro, mint, or a mixture)
1 small (2") peeled lemon, with pith, halved lengthwise
2 small (3") green apples, cored and cut into eighths
1/2 large English cucumber, quartered lengthwise
1/2-inch piece of peeled ginger
Tips: Alternate hard fruits and veggies (apple, celery) with soft (lemon, cucumber) when pushing down the tube. Best to end with a hard veggie like celery or carrot to "clean-out" the auger. I place the filter directly on top of the juice collection basket (the smaller one, closest to the base), even though the manual tells you not to use it during the juicing process.
To clean, I disassemble and soak the parts in a bowl of hot water (the prep bowl works nicely if you're using one) while I drink or bottle the juice; then give the parts a quick rinse and air dry on the dishwasher rack.

This is my first juicer and I am thrilled I made the right choice. I researched for about a month before I got my tax return and pulled the trigger, and it has turned out to be a great investment in my health. The machine is extremely durable as it has a full 15 year warranty. This is exactly the same model as the Omega J8006 that everyone loves so much (according to reviews) with the only difference being that it's white. A cosmetic difference but I'd rather keep the 40 bucks and be a little less fancy personally. Works great with everything I've thrown at it so far from wheatgrass to celery to carrots, apples, yams, pears, kiwis, zucchini, ginger, you name it. The only exception and this was an early mistake I made after I first got it and that is you don't want to juice bananas. Too mushy and just makes a mess. Extremely easy to take apart and clean though so within 5 minutes it was clean and ready to go again. Pulp comes out very dry so it is very efficient as well. All in all I think this model is probably hard to beat. Seems like it will last forever. Super easy to clean. What more could you want? 5 stars easy
