MarkC sold one on here recently for $2500. Playfield was in VGC and gameplay was perfect. Needed decals (which are available) and a shooter and it would have been a very nice game. From a dealer I would expect to pay $3000 to $3500. Privately I would expect to pay somewhere between $2300 to $3300. Cab decals suffer from fade badly on these and watch for decal wear too.
