Best finds at garage sale or similar establishment

I recently found a 1990's model yamaha cassette deck (three heads, bias control, etc.) at a goodwill for $13.00. While clearly out of step with my VPI, VTL, and Martin Logan gear, I still listen to tapes in the car and wanted something decent to record some of my 4000 + Lp collection. I find it remarkable that something that cost so little can provide so much pleasure. I was curious if any of my fellow goners have had a similar experience with cheap finds.
