If he is willing to spend a little more money and get acquainted with a tech, he could call either Action Pinball (Ray) or Mr Pinball (Daina Petit).
I would wave him away from a guy named Mike W in Park City. He is arrogant and is more trouble than he offers IMO.
If he is willing to meet some of the pinball natives, which I recommend, there are a few guys and gals here who are more than qualified. Perhaps they will chime in.
