pawn shops are frigging incredible, in my estimation. for music gear (i'm a musician), video games, and dvd's, i've had nothing but good luck. got my platinum gamecube, with two nintendo controllers, for $80 at a time when th ey were going for twice that, used, with one controller... also got countless movies and games for cheap, and some pretty good music stuff... some vintage keyboards and effects boxes, where they were too rare to easily find a price for it, so they just sold it for super-cheap.
then again, they aren't good in every city... i split my time between nashville and miami, and nashville has about 9 or 10 worthwhile pawn shops where miami has only one... maybe two (lots of jewelry only pawn shops, but they don't have anything but, well, jewelry). a good rule of thumb is that they're always going to be close togehter, though... and in pretty bad neighborhoods, usually. see if your city has a cash america pawn (they're ubiquitous, and pretty good), and there will probably be a couple more local shops nearby.
