Nino, I like what you have written. You were lucky enough to be involved heavily in pinball from an early age, and have a very extensive pinball history/knowledge compared to alot of us.
I wish i had of started collecting 5 yrs ago instead of 2 n a half yrs ago. I would have 120 machines instead of 30. lol
The prices today are pretty good if u study the market and contact 20 sellers and ask about the same title, condition and availability.
Its about hunting down who has what, how long they have had it, and target/buy machines that are not on everyone elses "hot" list.
