In all honesty, I'd think you might be better off going with third party flashes as a replacement. I have and use Metz flashes, fully compatible with Canon E-TTL as slave and master with bonus of optical trigger built in, that cost considerably less. Parts and repair costs are lower, though I've yet to need either it was something I looked into before buying the first one. The brand recommended by 'The Strobist' are a lot less money as well. Not sure about cheap imports, though I do sometimes wonder what brand names they produce other than their own. The prices sure are a lot more attractive.

Will any off brand function as the 580ex II does (did) as master w/ my 430ex II? Or, would I be better off selling the 430ex II and buying two non-Canon flashes that are compatible? I have never looked closely at other brands and do not know what makes/models are the best bang for my buck that will function for me like the 580ex II and 430ex II should. So, I am very open to any suggestions.
