BTW, these forums are the best I've found on the web for photography criticism and tips - thanks in advance.

I'm a web designer and graphic designer by trade but recently purchased a Sony F717, which I'm totally enjoying. I'd love to add an external flash that (a) gets the job done and done well, and (b) is fairly affordable.

Does anyone have any recommendations for the flash? What would you buy if you owned the Sony F717?
