The thread below about the 20d flash reccomendation and whether the 580 or 550 was the way to go sparked a different question of my own. I didn't want to thread crap that thread.

I recently got a 10d to supplement my film 10s. I have a 430ez speedlite... Someone in the other thread mentioned problem with the 420ex is going with manual is difficult with that flash. For that reason they reccommend going with the 550 or 580 (the e-ttl 2 is at this point anyway a nonissue).

My question, I suppose is, would I be okay going with the 420, and using my 430 when I want more manual control? or should I try to sell my 430 and get the 550/580?

Has anyone used the 430 on the 10d? I haven't tried mine yet, the manual only scares me a bit at this point...

I know this is a rather strange question, but I"ve been going back and forth between the 420 and 550 for a while now. I am very much an amateur enthusiast, and will forever be, I keep thinking the 420 would suffice, but I keep getting dragged into the specs and functions of the 550...

another side question, would my 430 be better suited to the 10s, because of the a-ttl, and the 550/420 etc. be incompatible with it?

any advice would be greatly appreciated!
