Pinball machines where designed for commercial use. Nowadays though, it seems like the only machines out on location are the modern Sterns. I think Williams and Bally machines are at least twice as fun and much less cheaply built. So that got me thinking, what Williams/Bally/Midway machines would still do well on location? Would the cluttered and finicky Twilight Zone survive the location test? What about Cirqus Voltaire or Theater of Magic? Honestly, I would love to come across some of these machines on location (only a dream of course). But if it were to happen, which machines would survive the stress?
Sidenote: Assume the machines that would be put on location have cliffy and mantis protectors and any other aftermarket mods that improve reliability. (For example: the extra clear plastics that prevent ball hangups on CV)
