Will your record store not put on a record for you? In my experience, most (good) independent record stores will put a used record on for you to hear. I remember one time I was picking up a used copy of Prince's Parade and there were 2 copies that were graded differently and with ~$15 price difference. I couldn't visually see much of a difference so I asked the guy and he offered to put on the less expensive one to see how it sounded. Out of maybe 6 record stores I frequent in my city, I can only think of one that probably wouldn't play a record for me - not cause they're junk but b/c they're larger, a chain, and may not even have a set up for it (I don't know, I've never asked there - this is speculation).
