thanks. I can only find 550 used and for >$180. and I don't want used flash.
I very seldom use hot shoe flashes, so need a cheap main gun to use once or twice a year and ideally another tiny one for hiking to pitch in in place of the build-in. having trouble picking either...
for a new flash under $200 you have but few options. in fact, the 568 is the only one that comes to mind as a candidate. If you read widely you will find that all experiences with thephotogadget are positive - including the situations where folks were hit with the dreaded "over exposure at 1/250th" problem.
the Phottix is probably a very good bet, but its twice the price of the Yongnuo. Others are emerging as folks figure out how to reverse engineer Canons system. no complaints here; in fact I just ordered two more!
