I am actually a newcomer to the Turbo scene.  Actually I knew about the games, but when my father asked me if I wanted one, I told him that he didn't need to spend money on it because I had other systems.  My first and second Turbo Duo system I have are new.  I mean the first one is now opened and used, but the second one I left sealed.  If I got it back then as a kid, it would have been not in the same condition.  I kind of lost my Super nes collection to my half brother.  I had 60 odd games.  We live seperately.  I just wanted to know how much someone would pay for it.  I actually left both of the Turbo DUo boxes in it's shiping package.  The one I opened I replaced the shrinkwrap.  I could get $800 or so now even though I got it recently, I wouldn't discard it.
