Oh yes.

I'm looking at restoring an old Gottlieb 1973 Pro-Football.  Not because the game is great, far from it, but because I have had this machine since I was about 15 years old.  Me and my friends played it to death in our teens, literally till I didn't know how to fix it anymore.  During the early 80s it was a big deal to have a pinball machine at home.  (My parents got if for free).

I'm happy to restore it knowing it will never sell for what I spend on it.
