Price guide and factors to consider.

Maverick - 2250 to 2500 tops. Working paddle wheel motor and 100% working display. Below 2k for a beater with stuttering paddle wheel motor and display with missing lines/burn.

Addams Family - 5000 for average condition and work up from there. $6k for better than average but unshopped, $7k and up for a restored one with extra aftermarket addons. Biggest price factor with TAF is the degree of playfield wear as replacement playfields are almost non existent and playfield repair can quickly add up if using a 3rd party.
