I have a rebel XT and three non-L lenses, the 75-300, 50 1.8, and the 17-85 IS. I have read all over that a good flash is better than any two or three lenses. I now see what they mean. I was always "happy" not "ecstatic" with the pictures I had taken in the past. (Close to 30,000 on this body BTW) I always shied away from using the on board flash because it is so AWFUL when it comes to quality. This lead me to using the larger apertures on the lenses I have, and the higher ISO settings to get the exposure I want. Well, lenses aren't at their sharpest when full open. Enter 580EXII. Set it on manual exposure, dial in 100 ISO, 1/100 f8 and shoot away. This gets the lenses comfortably into the middle of their aperture range for their peak sharpness. This also gets you to your lower ISO ranges where the (Already Low) sensor noise is minimized. It is a thing of beauty. I took it on out first Disney cruise, and in a variety of conditions it excelled. I can almost believe there is a little professional photographer inside there making sure my exposure is correct every time. The bounce flash works like a charm. Any time there is a ceiling within 12 feet or so, it will work beautifully. Only issue I have seen is bizarrely decorated ceilings with lots of wood and figuring (think Disney ship level of decorations) or blacked out ceilings. These both can cut the reflection level to a point of uselessness. The bounce reflector does a good job of setting up a catch light. I am thoroughly amazed by the small nuclear detonation that this flash puts out with a +3 flash exposure set. I have no doubt to its power claims. the focusing aid is almost worth the price alone. I can take a picture in thee FULL dark, with no epileptic flashing from the on-board flash, with instant focusing lock and perfect exposure. Incredible. I have not had a chance to use any of the advanced stuff like the wireless, external battery supply, or PC cord.
Problems:
First one isn't really a problem, it is a big flash. You knew that going into this, but there is no denying that it is a big flash. If you are used to holding the camera by the zoom/focus ring on your lens while carrying, it is going to flop around from the weight of the flash.
Does not degrade well when the batteries get low. It has no visible battery meter either. It just starts behaving erratically. Not flashing, not going into ETTL mode. It would be nice if it just shut off, or flashed the word "battery" or something on the LCD
If you plan to use the custom functions, you better have the manual handy because they are labeled "Custom Function 5" and that is all the help you get on what it does.
Overall, I LOVE this flash.
Update: 8/31/2010
Guess what? This flash is not gravity proof! While at a photo shoot, a rogue gust of wind tipped the light stand and umbrella with flash over onto concrete. No flashie anymore. I opened it up to see what had happened. The bulb had snapped in half. I think to myself, buy new bulb, internet is a big place.... Alas, no. The 580EXii does not have a replaceable bulb, it is soldered in place, and not for sale. Ahh well, a $120 trip back to canon resolved the issue. I must say they were very fast about it.
I still LOVE the flash. I have had the occasion to use its wireless functionality with other canon 580EXii's and it works pretty well.. Full ETTL control. You have to be a little careful about getting them to see each other, and the range is only 30 feet or so out in the sun. Its a LOT cheaper than a whole set of pocket wizards, and more reliable than "pocket change wizards" (ebay wireless triggers)

Honest Review of the Canon 600EX RT Speedlite
Laura Gordon
nice flash with reasonable output, expensive
Bought this flash yesterday, to use primarily with my also newly purchased EOS Elan 7NE 35mm SLR. I kept deciding between 430EX and 580EX II and I don't regret buying this model. The flash is not too bulky or too heavy as I was afraid after reading some reviews - my previous flash was Vivitar 285HV, and it is quite bigger and heavier then 580 EX II.Now, the flash output of 580EX II is dependent on zoom setting of the flash head. The advertised GN190 sounds like vast load of power, but it is a guide number for 105mm zoom; when you use 28mm lens you get only about GN100, and GN140 for standard 50mm lens. It's off course not bad but not the GN190, so don't think that you'll flash an entire concert hall with this flash. I did a test roll on full auto setting on the camera and E-TTL II on the flash - while working nicely and quite dependably out of the box, to my surprise the flash and camera use quite wide apertures, around f4-f4.5 for most exposures indoors.. I realized that I'll have to use full manual mode on the camera and E-TTL II on the flash in order to obtain smaller apertures and get more DOF - in this setting the adequate flash output will be provided automatically to accommodate the selected aperture (and shutter speed) setting.I didn't even remotely touch all the features that this flash offers, although I did go through them briefly while reading the provided user guide. I think that the flash will serve me well down the road, and it is better to have that extra output over what 430EX would give me. Finally, I believe that 580EX II was released very recently, while the 430EX is couple years older. The built quality of 580EX II is generally nice, the hotshoe is metal with locking lever, flash has external PC connector (which 430EX lacks I believe); obviously the 580EX II has more to offer. BTW, I'm amateur photographer.The main drawback - price is steep. If you don't need all the features (there are tons of them), you may be better off with the cheaper 430EX; I grabbed 580 but mainly because I wanted the PC connector since I intend to shoot it occasionally with my other cameras in full manual mode off-camera on the stand through the umbrella and such - so that's why I wanted maximum possible flash output.One last but important thing - I called Canon technical support today with a question regarding the use; good news - Canon techs are located here in the United States, are friendly and knowledgeable (so, don't worry about having to deal with overseas-outsourced tech support, which can be quite a horrible experience)
