Unless it was a pretty high-end camera body like the eos 1v, I think the market for the camera body is probably pretty slim. Likely less than any sentimental attachment you might have for it. The reason being, DSLR's are so cheap now, and offer so much to the user, that you need to really want film for something specific to shoot it. And those users that do have their pick of the litter from older equipment. Lenses could be a different situation, depending on their quality and if they can be used in modern digital bodies -- the bigger the market, the more you can probably get for them.
