I think that a good machine would do really well in any number of the local taverns/bars where I live. I would imagine that maintenance costs have skyrocketed due to their current scarcity. Maybe they'd make a comeback if they could be combined with the payout concept of a slot machine. Maybe it would payout if you got an obscenely high score or something to that effect; although it wouldn't be financially feasible for the owner if a pinball wizard came and cleaned out your machine all the time. Then again, pinball wizards aren't in it for the money. Then again (again), maybe I've hit just the right note to bring the pinball machine back?
No matter where you go, there you are.
