Just be careful when dealing on GEMM, Musicstack, and ESPECIALLY E-Bay. There are tons of sellers out there selling used "mint" or "near-mint" vinyl that's not suitable for use as a frisbee.

The criteria for most vinyl sellers on e-bay to qualify as "mint" must be that it's still in one piece.

A couple of sellers I've had consistently good luck with are www.recordsbymail.com and www.all-vinyl.com
