I've been looking at alot of different cameras online and have decided to upgrade my point and shoot for a DSLR. I have a limited budget, and these cameras are very expensive so I thought that I would try my luck at the local pawn shops. I found a Pentax K10D 10.0 MP with 12x optical zoom for $489.00. The worker at this pawn shop said that they would for sure take $400.00, and may come down more. Is this a good deal on a used camera or should I hold out?
