omg, you live in vegas! there are amazing pawn shops there (or so i've heard). you should try the one that's behind toilet toilet...uh, i mean circus circusi have heard that pawn shop is notorious for hot items like rolexes, et al. desperate gamblers wanting to pawn their expensive wares for gambling!
even though it's been many years since i have been at that part of the strip, i don't know how seedy it is now. but i know vegas has a lot of them, you should just check them out.
