Bought the second model of the Sony Betamax VCR at a thrift shop on the Oregon coast. It was dusty, but otherwise in perfect condition. Gave it a good cleaning; and since I was in the professional video editing and distribution business, I was also able to test it for playback and recording quality. It worked perfectly, though the mechanical switch contacts needed a good cleaning.
Had it in my office as a display piece for a few years. Eventually sold it to the manager of a local TV station that collected vintage video equipment. Sold it for $500.00; which was a huge markup from the $20.00 I originally paid for it!
