I'm just pleased to hear from someone who digs on pinball. I got hooked on the silver ball back in college, and now days it is tough to find a machine -- especially one that's well-maintained.
Do you actually own your own? Adams is a great pin, but I'd settle for any of the Williams machines from that era. Twilight Zone is probably my favorite. I almost purchased World Cup Soccer, but I couldn't figure out where I'd keep it in my house!
