I don't know when it happened, but eBay has RESTORED the 'Commodore' category under 'Vintage Computing'. It had been eliminated a couple of months back. Most of the Commodore items are still listed under the parent 'Vintage Computing' category, so you'll have to continue to check it, too, until people notice that the Commodore category is back.
Woo-Hoo! If we're on the eBays, we ARE SOMEBODY!! :)
Interesting. Now I have to go and revamp my searches. :(
