A IK16, FlashInvader is for sale on Drouot.com. It will be auctionned on the 8th of July.
It looks nice, but as for us the signature is very doubtfull. Except if the auction house is providing original invoice + packaging from the Space Shop, we strongly recommend not to bid. That being said most of them will tell "we have expertised it ..." but are not keen at all to provide any document ...
