Best finds at garage sale or similar establishment

I bought a box of LPs (82 total) from an estate sale for $12.00. I kept 51 of them that interested me and were in pristine condition and donated the rest to Goodwill.

Found 10 DECCA WIDE band LPs.

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!
