Good deals do come up but as previously stated you need to be ready to jump in the car and go. If you find something online (i.e. Craigslist) and you actually are the first one to contact the seller and make a verbal agreement over the phone, ask the seller to remove the listing from Craigslist. All to often other pin enthusiast will call the seller and offer more money. So many stories like this on Pinside where people drove to the seller's place only to find out that someone else offered more and he seller took it!

Not sure it was asked yet but are you willing to learn or know how to work on machines? If so GREAT! If not then you want to consider that you're going to be paying someone to fix it and it can be costly! It's a steel ball bouncing around a playfield full of plastic parts......it's going to break! Heck you can go pickup your first machine and everything is good then you get it home and it's not working! Not trying to scare ya .... it's reality!
