Not sure what's going on there.
If I enter the item number then I find it. If I search for Amigaone (even with description included) all I get are a couple of Blizzard boards and a t-shirt. I even tried to copy & paste your header into the search bar jsut in case you had a "0" (zero) instead of an "o", but it still wouldn't come up.
Very strange. I'd contact eBay.
