AFAIK there is a huge stock of these things somewhere in China, and the seller called xiclaus_cd has been selling them for over a year now (maybe 2? don't really know).
I've heard of a few people who bought one and they are indeed New In Box, although I also heard stories that they just come in a brown cardboard box, rather than the original printed CD32 box. But still, the machines are completely new and unused.
I think you don't have too much risk if you want to buy one of these....
