Yesterday a Commodore 65, a rare unreleased prototype by Commodore, was sold on eBay for $9,100! You can follow the story on the Lemon64 forums. The seller, Dimitris Podaras, had bought TWO of these rare machine about a year ago, on eBay also, for $5,000 each. He just sold them both, this one with a nice profit!
One day we will know who bought the other one… ;-)
