Now that I have resurrected a Bally Fireball and Time Zone from the dead, I'm curious what people consider to be the top 3 Bally EM pinball machines. I am growing fond of Bally EMs and find them pretty easy to get working. I haven't played very many Bally EM's (I need to play more), but my top 3 are:
1. Fireball
2. Old Chicago
3. Time Zone
