An incredible eBay auction that is worth looking at: over 1,700 pieces including some random handhelds, TV games, Texas Instruments, yadda yadda. Most impressive is the seller's painstaking listing of every item, lovingly crafted by an obvious game fan. It must be really hard for this person to part with all this stuff, but I'm sure it will find a good home. Current bid: $7600. You must REALLY like games if you want to buy this collection!
Thanks to Gideon for the head's up.
