Having bought my Blu Ray player, I'm ready to go out and buy a ton of discs, but budget doesn't allow me such luxuries. Fortunately a lot of pawn shops in my area have used discs for $10 each and I went ahead and bought my first used one. This might well be my last. It had some scratches on it, but I figured I've bought DVDs with scratches on them and had no problems. They weren't even bad, just surface scratches. The disc locked up about 8 times and now I'm going to bring it back. What a waste. Anyone have bad experiences with scratches on these things? Any advice?
