A long time ago....I bought a camera.

So I have hit that point where my camera is about to fail me. I have had my Nikon D-200 for going on four years now and around 30,000 shots taken with it. It has recently started going soft and producing a large amount of artifacts in my photos. IT's time, I don't want it to be, but it is. Time for a new camera, including long nights of research and scratching togehther every cent to write the probable $3,000 check... I'm thinking D-700.... Anyone?
