^This. I have two PRS SEs I bought used. One was $350, the other $400 (but that one was only two weeks old, so basically brand new, with shipping carton.) I've seen a few SEs for $300. Tremendous value for the money.I did get a PRS for $300. It's a 2001 PRS Santana SE with planet waves locking tuners and Seymour Duncan '59 in the neck and a Custom 5 in the bridge. This is the best $300 I own. I always think that you get the best value for your money when you buy used.
Early Peaveys like the T-15; they can be found pretty easily for $300. US-made guitars with excellent Fender-ish tone and solid construction. They can be heavy, but that's the worst thing I can say about them. I found my 1994 Peavey Foundation bass for $180, and I've seen some for even less; it plays like a J-bass, with a slightly more modern sound.
