What Lloyd said: Find some machines you can play without having to provide care and feeding for them. That would be friends' games, location games, or show games.
Then, generate some income, be it mowing lawns, developing a killer app, whatever.
Negotiate an agreement for some space, be it at home, or in someone else's garage, whatever.
Depending on how well you did in the income generation department, look for a cheap and easy restoration candidate and learn about pinball by bringing ta back to life, then trade up for a more expensive cheap and easy restoration project. Repeat as needed until you have the game you want.
I would suggest that your best bet at the moment, though, is to find some games on location. It'll keep you hungry for it. If it doesn't, then you got to learn that without dropping big coin on something that you don't really like much after all.
