Well, after a pretty grim day of thrifting, I picked up a probably overpriced Philips CDi 220 of unknown working condition with a Digital Video Cartridge and two controllers for $25, an awesome loaded 1996-vintage P1 Win95 PC for $15 (I needed a legacy system badly), a Mac powerbook without power cord for $10, and I found a copy of Atari Video Cube bundled with 5 other games for $3.
I did pick up another 10 nice "black" 40's jazz 78's, which are worth nothing according to eBay but that I still enjoy. Someday someone is going to appreciate these with some dollars.
