I'm surprised nobody has mentioned Better Records. Don't let the expensive "hot stamper" pressings put you off. Tom keeps a lot of modestly-priced stuff too. I've picked up some very nice Bill Evans and Blue Note stuff from there. Tom's bag is that a carefully-selected conventional pressing will often sound far better than the heavy-vinyl reissues. Truth be told, I've never been enamoured of most of the heavy vinyl, outside of the looks. Anyway - lots of good stuff, great service, AND, for $5 he'll clean the record for you on a VPI machine. Well worth it if you don't want to invest in a machine.
