The question that I have for you is what experience do you have shooting Nikon bodies and if you have experience with other Nikon's, why do you prefer the FM3a? I have shot many Nikon F's, F2's, Nikkormat's, FM2a, FE2, and currently like the Black FA very much. You would probably be able to pick up a nice used FA for a fraction of even a used FM3a.
