I have 430EXII for 3-4 weeks really love it. if i have more money (long wish list, lol) i would love to have one more.Just wanted to shard some thing.
Buy 480exII if you wanted a light kit and small for easy to store and use for long hours, shot a lot of indoor, use for short to medium rang flash and if you plan to own new DSLR like 60D or 7D in future (can use as off camera flash for Portrait wire wireless).
buy 580exII (mother ship
by photofreak99 (good one) )
If you don't care about a heavy and large kit short a lot out door pic, use it form short to long and don't want to own both of this DSLR than this might good for you.
P.S sorry for this one swatpup32 you don't have to see this part
