Picked up a used one at the local Goodwill store fore $10. The only issue with it is that it has a broken tuner circuit board which prevents the ability to find AM/FM stations. Out of 12 FM presets only one was set to an actual station.
I manually changed the speaker impedance from 4 to 8 ohms and hook up a nice pair of Infinity speakers and boy does it sound great. Full vibrant sound field while playing either CDs or Vinyl records.

owned for 2 years, daily use. drives Cerwin Vega VS 4ohm speakers and Bose 101 outdoor speakers. handles the low ohms. rated at only 45w x 2, but loud. Simple presets for radio. Needs a good antenna to pull in stations. Durable.
