It has been years since I've spotted a bargain on eBay before somebody else snatched it.
Today I picked up two $100 IIgs units. One appears to have a Superdrive controller and a microdrive. The other has a ZipGS and a 4MB RAM card.
I've always wanted a Superdrive controller, but was never willing to pay the going price. I don't have a Superdrive though. I don't suppose I can just put a 2MB floppy mechanism in an 800K drive, can I?
