That was user Otto** that offered one for trade bait.
I've played one @ Expo couple years back. While it's unique (playfield layout), I definitely think you would get burned out pretty quick. Let's just say if you have room for twelve pins, I still don't think it would hold up in the lineup - maybe 20+?
I've seen a few collectors have them. Mainly the Gottlieb fanatics. I guess the real issue were the backglass on these. Most of them are flaked badly...
