Ive got a chance to pick up a used 30D without any glass, and some random extras, BG-E2 grip, spare batteries etc. Hes asking $475, i think its a pretty decent deal, only wear on it is on the flash mount and the bottom from the tripod. 15,000 actuation's. My question is, 1) how good of a deal is it really and 2) what would be a decent beginner lens, size, make f#? Mostly will be taking pictures of cars, racing, parts, a good bit of macro's, some distance but nothing major.
