Just bought the sucker:
Someone on ebay is selling them $15 shipped to the USA. It may be an early model with a later version getting more improvements, but as is, this can boot ISOs and backup saves to / from SD cards. I might as well take advantage of a prefab while it's available. The software it uses is used for other purposes among the Saturn community, so even if development stops on this thing, it should still work.
That seller also has a bunch of other mods he / she makes from designs on the net, if you want to add anything else to your cart. I'm not afraid of losing $15 even if the seller sends nothing / is a scammer. I sell on ebay all the time and let me tell you, the buyer has the seller by the balls--not the other way around. It is much more of a hassle when a buyer scams you. As a buyer, you can say anything and ebay will force you to refund. Even when a buyer does this multiple times (as reflected by their un-redacted feedback), the buyer account still remains up.
