Quoted from Eskaybee:
Stern thrives on their games being easy to maintain for pinball. But for a couple thousand more dollars we can buy a JJP game and be locked into doing maintenance + tweaking every other nigh.
You’ve hit the nail on the head with JJP games, they are a maintence nightmare that won’t go away. And as far as warranty service goes, good luck trying to get an answer on a ticket.
