Are there any Canon experts out there who can help me with this? I have a friend who is looking for one of the above units, but she is having a hard time telling the difference. I found a web site that basically said that the 430EZ replaces the 420EZ and that the 430EZ supports flash exposure compensation. It sounds simple enough except that KEH has the 420EZ at a substantially higher price than the 430EZ. Is there something that anyone knows to explain this? Am I missing something that makes the 420EZ worth about 30-40% more than the 430EZ? By the way, the camera it will be used with is either an EOS 630 or 650, I can't remember for sure which one she has.

Thanks!
