Can't beat Jilly's prices but some of their pins need some work and have for years. A few friends of mine have offered to help tech for free, but they turned them down. They usually get one new game a year, and at 25 cents a play you can't beat it.
Some issues from the last time I was there a few months ago:
Pirates of the Caribbean (not working)
Monopoly - Bank Door intermittently working
Monster bash - Kickout hole throws it SDTM
Theatre of magic - Trunk was having issues
Simpson’s pinball party - Upper flippers did not work
Star Wars stern - Not a maintenance issue, but it is running older code (No video mode, lightsaber duel, etc.)
Aerosmith - Toybox gets out of sync after locking 2nd ball
Dark Knight - Weak flippers
Ghost busters - right ramp switch doesn't register; running older code so you can never finish/time out Spook Central
