All Canon EX are the same (including the 580EX), E-TTL on older cameras and E-TTL-2 on the newer just released generation of bodies...

It's Guide # is 58 as compared to the 55 for the 550EX. It does have a newer feature which adjusted for the cropping factor on the 20D so that the zoom head is right-on instead of having an 'overspread' beam like on the older flash when they zoom in for the tele (wich did not accounted for the crop factor). The 580EX can also compensate for the white balance, but then the Metz is also quite accurate at this...

I don't think you can go wrong with any of them (even with the inexpensive Sigma)

They key with any flash is you: understand how it works with your camera, understand the metering setup with is advantadges and disadvantages. They key is to know both and figure out how to use the advantages to get he best shot and know the disadvantages so you can avoid the problems by making sure your setting account for the event that is going to happen.

IMHO I would go with the 580EX with the CP-E3 battery pack if your unsure, its the safest setup with the least expensive high output battery pack.

Me personnally I am going with the Metz 70MZ-5, and 2 580EX speed lights with 2 CP-E3 battery pack and some 8 battery clips for each of them becuase I can use the 2 of the 580EX's on tripods with softboxes around them and the ST-E2 wireless transmitter to set them off. while I can use the more versitle Metz 70MZ-5 in a task that requires more mobility.

Thank you all for your input, but I did notice one thing, nobody really mentioned the Canon flash, so does that mean it isn't worth it? One other question about the Metz, does it have eTTL-2?
They all have E-TTL: the eTTL-1/eTTL-2 comes from the camera algorithm not the flash - ie put a 550EX on a 10D/300D it's eTTL-1, but when used with a 20D/XT it's eTTL-2
How can they all have E-TTL, then wouldn't the cheap'o flashes at Wally World adveriste ETTL.

We're talking about the Canon, Metz and Sigma here... Even Canon older flashes do not have E-TTL
