I never played that Simpsons pin before so can't help too much, but I do have a PZ. This pin is good clean fun, read my rating for more info on it, also watch for Captain Bzaar's moving head (it follows the ball around the playfield and talks at you) this constant moving mechanism is likely break solder joints/wires on the coil lugs for the mouth action. I was forever re-soldering these back on, untill one day I ran these wires through the plastic base of the coil (I had to make holes) and that was about 4 years ago, no probs since.
