Haunted House is one of the best pins Gottlieb produced. The system80 pins can be difficult to keep up if you don't have the ground upgrades etc. done; so long as you do the ground mods etc. they are VERY RELIABLE. I own and have owned a system80 pin and shortly after joining this forum I learned what was needed to keep it in good shape. I 've owned an HH in the past as well as Blackhole and believe me when I say they are worth any problems you may encounter, very challenging play, yet not so deep of a rule set. If it's in very good shape it may be worth more than 1500 but it would have to be very good. I would also tend to think a pin kept in that condition would already have the mods done or perhapes have the pascal boards. I'd ask those questions first.
