I can't play this type of box so don't want to buy it I'm afraid, but ... if I was looking to buy a new box I'd want to know more about it, to stimulate my interest as it were. What's the keyboard like e.g. responsiveness, what colour is it (that matters to some people), tell us more. If you can post a link to some pictures too that would be good. Personally if I'm looking, I'm impatient and just want to see it, now.
Good luck selling it though, it sounds like a gorgeous box.
