Your best, and safest bet is guitarcenter.com. They have a vast inventory of used drums, and you can specify the price range, condition, and even location.

Shipping is a little bit (depending on where the drumkit is being shipped from) but completely worth it because you also get a return guarantee.
Just do your research online for each drumkit that you are scoping out. You want to find out what type of wood the shells are made of. The more you know about drums the better decisions you can make.
Plywood is going to sound crappy, so stay away from the pearl Exports the Gretsch blackhawks, gretsch energy, and stuff like that. If the type of wood that the shells are made from isn't mentioned, then it's probably plywood. And that sounds like a tin can inside of a wooden box!
Maple and Birch are the best shell woods, or "tone woods" for drums, or even maybe a blend with Basswood. All Basswood shells are also really good.
The kits (in your price range) that I really like are;
PDP platinum series
PDP CX
PDP F series
Premier Artist series
Premier Genista
DDrum Diatribe
DDrum Diablo
Gretch Catalina Club
Gretch Catalina Club Rock
Mapex Meridian
Mapex Saturn Pro
Mapex Mars
Mapex Pro M
Yamaha Stage Custom
Tama Rockstar
Tama Silverstar
All the best.
