Cassettes are fun.
If you go to thrift stores, or Goodwill, or second hand stotres, or Salvation Army stores;
you can find a three-head cassette deck for less than $10, or $15 at most.
Get a single door one, not dual, not auto reverse, just a simple three-head deck, with dual capstans and three motors.
Look for brands like: Nikko, Denon, JVC, Nakamichi, Akai, Teac, & Marantz.
* Often, you just have to replace one of the rubber belt (very simple to do and cheap to buy from the internet).
** And if it has stereo mics inputs, you got yourself a recording studio that you can use as a preamp for a CD recorder. So, if you're a musician, it comes very handy. And you can use the Monitor function as a good guide from this three-head deck.
Happy hunting to whoever is looking for one.
