+1 for contracting with an operator. Every restaurant/bar owner I know has little time to deal with some of the challenges that pinball machines bring. They can become a real PITA, even for experienced technicians. A non working pinball is also a poor reflection on the restaurant/bar itself. Why concern yourself with pinball tediousness when you can focus your energy on B I G picture things and get paid to have someone route their pinballs in your establishment? Do what you do best and outsource the rest. Just my .02

For my route I like to compliment a newer game with an older game. I have a Deadpool and a Tales From the Crypt (for the month of October) currently at a brewery and they get played quite well. My theory is that an older $.50 per play game up sells the the newer pins that are $1 plays. I trade the lesser expensive game in and out as the ROI is usually a lot better and it keeps things fresh while I chip away at that NIB Stern. Good luck and hope everything works out
