I very rarely buy used now except from forum members who are generally trustworthy,I used to buy from e-bay,but mostly from a seller who lived local to me and I could inspect them at his place.Since the demise of "Criminal Records" in Tunbridge Wells I haven't purchased anything used.Some of the crap that seems to be sold at some remaining dealers defies belief.
I once pointed out to a dealer based in shop in Essex that a Tangerine Dream LP I was considering purchasing on inspection had a scratch right across the b side,he just shrugged and put it back in the rack,needless to say I walked out.
