The local CL has a 30D in "like new" condition (the pics do look pretty good) for $250. The folks on campus are usually good to deal with because they'll come to your office so you can test things out. If this 30D is, in fact, like new, it seems like a pretty good deal for a 2nd and/or MF dedicated camera. I've been browsing the 30D forum at POTN and it looks like it has great IQ, even at high ISO.
