There's a retro store in Chicago. People Play Games. They've got one there, boxed (like the original one) for sale for $200. No clue if that's a decent price or what you are looking for. If for some reason that's what you want, and the right price, happy to pick it up for you and ship it (w/ a receipt proving you paid me exactly what I paid for it lol)
P.S. I don't work there. I just buy too much crap from them
