I realize this is 3 years old but if you still haven't sold it I'm willing to buy only the first Tomba for $15. Pm me or whatever if you're interested.
if these were complete it'd be a good deal, but I think most people won't buy both in various conditions. I'd recommend trading them on goozex personally . You can get $100 worth of points there (worth 1000 points each ($50 each) which can get you two new releases).
