Thats not a bad price for it at the moment if its uber rare but then there is over a day to go so it could go up really high. Never ever heard of or seen these but then I live in Europe so that would explain it. If only I had the money as I've always wanted to get a Mega CD add on for my megadrive to play Sonic CD
I remember seeing loads of those mega cd all in one thing in some brochure I had at the time. Or maybe it was the manual for something? I can't quite remember, but I remember being completely awe struck even though I already had a mega CD.
