I've had bad luck with used cassette decks. It seems like each one I buy second-hand from thrift stores either have sound issues when tested at home or soon develops problems. Spending $50+ on a mainstream Yamaha 2 head used deck on eBay that's been tested is kind of pricey for old technology. I know cassette tapes are pretty much dead, but isn't there a small and potentially profitable market of tape enthusiasts for companies to build a good quality 2 head deck mainly for playback and price it at $100? One would think that tape deck technology has advanced and been perfect to the point where someone could build a reliable, good sounding deck for $100.
