I am being serious when I say this. Search this forum for similiar topics. There is tons of great information in a lot of the past threads on this subject. Some past suggestions that resonate with me include

*PM local Pinsiders and meet people near you in the hobby.
*If you locate a game to buy, take someone who knows the hobby and what to look for if buying used.
*go to a pinball show to help you decide on what game...ie play it.
*be prepared that one game is usually just the beginning
*dont be in a hurry, the right deal for you will come along
*read up, looks like you found a great spot to do just that.

Good luck on a fantastic hobby full of fantastic people!
