My son does all my board work and he is constantly "pissed" at me for saving games he doesn't want to deal with but so far this year I have saved over a half dozen Classic Bally / Stern / and Williams titles that would have become parts if most people had purchased them.
Titles include:
Two - Stern Magic's
Bally Globetrotters
Williams Pokerino
Stern Dracula
Stern Gallaxy
Williams Flash
All these machine had most major stuff cut out of them - most were missing all boards & displays and some were even missing harnesses. With a lot of digging, begging, and help from the pinball community all these machines will live on. Every one was "suppose" to be a "parts machine" and in the end I'll be lucky to break even on any of them but at least they have all be saved to be enjoyed for years to come!
I buy 25 to 50 "parts machines" every year and I part out dozens of machines helping other machines live on. But I will never part out a machine nice enough to save regardless if I lose or make money by saving it. In the end enough of this machines have ended up in landfills already so we all need to save what can be saved.
