I only have a few gottlieb games on my list and this is one of em…. 5500 seems a little steep for a non-working game, but your right there really isn't much data to go on for pricing.
Hope this title pops up again in 6 months, when I have time to work on it.... I won't hold my breath.
Wish I was in this hobby 5 years earlier , the prices for these old ass games are getting high!
