Get lots of pictures inside and out. Also the all the circuit boards and post on here so we can see and give any hints or clues to what we see. Game play is out of the equation since it is 4 hrs away. But if you do go, play it and ask questions about the pin. I know it is tough to drive that far and not buy, it is a real bummer!
Remember all pins will need adjustment and fixed at times. Lots of help here on pinside!!!! I found that when I got into this hobby I knew ahead of time they would need fixed. And is one of the enjoyments I have is fixing and playing them!
Here is my F-14 at this time! Great game, wife loves it too!
