I was looking for a flash unit for my Nikon D60, and even though I have some in mind, I'm not sure of the capabilities and whatnot of the particular ones I was looking into. I wanted to know mainly about the SB-50DX...wouls it work on my camera? Is it any good? And then there is the SB-600 and SB-400...the 600 seems good although it is a teeny bit pricey and I heard that te 400 kinda sucks :/. In addition, does anyone know if any sigma flash would go good with my Nikon D60? Suggestions would be appreiciated 
Ty in advance
