The Prazi beam cutter is not a miracle tool. It won't give you ideal results without any effort or skill on the part of the operator but it is a valuable piece of equipment that can cut a beam easier and better than most alternative ways to go about the job.
I bought the Prazi beam cutter to attach to my old Milwaukee worm drive saw. It arrived complete and took about 25 minutes to install. If the instructions had been easier to interpret, the installation would have gone smoother. Never the less, if you are the type of person who is at the point of carefully cutting large beams in your building career, you will be able to figure out how to install this tool onto your worm drive saw, no sweat. The only major problem I had was the fact that the older Milwaukee saws do not come equipped with a blade lock button. In order to tighten the beam cutter properly, you have to be able to lock your motor shaft down. I ended up opening my oil filler hole in the gear housing and jamming a hardened steel pin into the drive gear. This worked well but I felt that I could have sheared off the pin with just a bit more torque.
Starting the saw surprised me because I expected an out-of-control chain saw feel to it but instead I was pleased with the speed and overall stability. I typically have been cutting 8 inch spruce beams. I always nail or clamp a fence to the beam to guide the saw. This allows me to concentrate on pushing the saw without worrying where it is going. Crosscuts (6 to 7 seconds per inch on my 8" beams) seem to take less effort than rips as I will often find myself pushing the saw hard on a long rip to keep things moving. The cuts are sometimes hard work -but a breeze compared to any work with a handsaw on the same piece of wood.

I got it in record time with cheap shipping and the price was great too.

I bolted it to a new Skil mag 7 1/4 wormdrive saw. The mag is not light by any means and it shook badly. After dismantling and reassembling no less than 10 times I determined the part that bolts on where the blade usually is was .010 loose. Fortunately, I had my vernier caliper stuck in there with the socket set, allen wrenches and a set of feeler guages now minus the .005 which is cut and wrapped around the bolt to take up the slop. Ah, smooth running, hardly.

The camillion chain starts to change color and begin smoking like the "Dice Man" unless you stop and oil the thing every couple minutes, some type of "rigged" oil feed is necessary. It is also necessary to frequently check the chain tension to avoid it's falling off. The chain tension issue is caused by the chain adjuster/tensioner being useless, not a screw like a real chain saw.

The vibration of the chain through the chain drive sproket produces volumous vibration and chatter certain to remove unwanted fillings from your teeth. It is impossible to keep the work area free of wood chips, I found the need to sift through chips to find bolts that continued to fall out even after they had been secured with thread locking compound.

Far be it from me to follow the safety instructions. I removed the safety bar for the plunge cut I was doing. When holding the saw in front of you the imbalance of the saw sends the 12 inch chainsaw blade toward your leg where a momentary lapse of attention could really impare/and or/improve your love life. Use extreme caution.

Time is money. A slightly better tool would be twice as fast. I rough cut 10x10 PT into tapered columns with square tops and bottoms.

I purchased the PRAZI PR2000 Beam Cutter for the expressed purpose of ripping 8' x 8" x 8" western red cedar beams down to 7" x 7" and for saddle notching the top of the beams to accept a 4" x 6" lintel. I found the PR2000 did a fine job on cross cuts but was not suitable for the end grain rip cuts. The tool became very difficult to control and hold on line and the tear-out is completely unacceptable. I am sure there are applications where this tool shines but for my saddle cuts and ripping applications in this particular material (Western Red Cedar) it receives a failing grade from me.

I was skeptical when I ordered this saw from Amazon a few weeks ago. BTW, Amazon has the best price on this, and appears to be the only way you can buy the PR2000 on the West Coast, lumberyards only seem to carry the worm saw version.
OK, the blade looks strong, its heavy and appears to be good quality. We have been using this to cut stair stringers out of 2x PT and it works great. By setting up guides, we accurately cut 6 - 2x12's at a time and they all come out the same in about the same time it takes to cut one. It saves a lot of time. The downside is that it makes a rough cut, very comparable to what a chain saw would do -- cause this is a chain saw for your circular saw. Therefore, you can not use this for open stairs or any finish work.
The saw is fairly accurate and easy to control, though as another reviewer said, you should use extra caution with this blade cause it could do some damage.
Overall, we have been very impressed, it is certainly worth the money.
