First of all, is it a turntable or a record player?

Secondly, especially if it's a turntable and not a record player (which would eat up your vinyl with its heavy stylus), I would second RI's recs. Anything 180 gram is definitely worth adding to your collection. Look for reissues of your favorites--as Rob says, there IS a difference.

Other than that, be careful what you buy used. I cannot endorse the recommendation to check out flea markets or antique shops. They are not run by people who know records. Those places are some of the worst for overpricing records that are so trashed they shouldn't be for sale in the first place.

Make sure you only buy from reputable stores that clean their used LPs before putting them out for sale, and that only sell VG-plus or better condition.

Thanks for joining us in the good fight, man!
