I have a Bandai Pippin @World with a 4 MB memory card up for sale on eBay. Bidding starts at $40 and the item will only be on auction for five days.
I also have a set of Two Japanese Eric Clapton Laserdiscs, a Yes concert laserdisc (1975, Live) set (which is apparently unofficial) along with a bonus Anderson Bruford Wakeman Howe: In The Big Dream LD. And there's three Playboy Laserdiscs, too. I dunno if anyone would want those. :P
So here's a link to my eBay stuff!
