Tough one to price - for example, I won one on Ebay for $1500 or so a couple of years back, and the seller backed out because she got a local offer above what I won it for after the auction.   That was non-working, decent condition. But that was back in the pre-GFC market I think.

I have seen two come up and disappear quickly a few years ago, presumably a nice offer was made.

Best playing system 1 around IMO, and outplays many titles of that era from any maker, if you like old school feel and drop targets.

Personally, as described $2,500.00 would be the minimum I would think if its that nice cosmetically.
