You will probably just buy whatever title you can find locally.
DO NOT BUY YOUR FIRST PIN SIGHT UNSEEN FROM THE INTERNET. You will get your ass ripped wide open.
Join the local pin league, keep an eye on Craigslist, look for LOCAL sellers on Pinside and MrPinball.
Have your cash and transportation ready at a moment's notice. If you have to wait until the weekend to borrow your brother's van, that game will be long gone. Even if the seller says he will hold it for you, someone else will call and offer $200 more than you, and then suddenly "Hey I'm so sorry, my wife won't let me sell it..... ". You don't want that phone call after getting your dander up for a day or so.
