I shoot mainly available light. My D200 is fantastic until I get to about ISO 800. I know about the D3s, but can't afford it. I have my sites set on the D700, but what about any other models. Right now I'm only thinking about low-light capabilities, not FPS, auto focus, or build. There's a lot of cameras that came out since my D200, expensive ones and cheap ones. Could anyone list them including the rumored ones(I know this would be a guess) according to low-light, noise so I could see where my D200 falls.
