Canon 400d Price

Robert asks…How Much could I Trade my Canon 400D In For?I have a Canon EOS 400D, it's about a year and a half old, in very good condition, and I want to trade it in somewhere for the 500D. I was wondering if anyone knows how much I'd roughly have to pay on top of the trade in? Or if it's even worth it? I didn't bother getting the 450D when it came out because the people in the camera shop told me the price wasn't worth the few extra megapixels, so is this the case with the 500D? Or are there
