I am about to go look at a Nikon D80 that I found in a classified ad yesterday. The camera is only a year old and he says that it is in perfect condition. I wanted to know if there is anything that I should pay special attention to (to make sure that nothing is wrong with the camera). Besides taking a few pictures and checking to make sure they look accurate, is there anything I should be cautious of. I have never bought a used camera before and want to make sure that I am not getting ripped off. Also, the sale is just for a camera D80 body only, with grip, for $700. I imagine this is reasonable since the camera is around $900 new. Would you consider purchasing if you were in my position, or hold off and wait until a "black friday" sale? Thanks for all of your input.
