I have a IPB MM playfield. I got mine right after they finished the first group of them way back when. The only issues I had were the super jets arrows up at the top of the outer loops were missing the purple on the outer edge of the arrows. There might have been a LITTLE touch up needed on the FIRE inserts too, but I can't remember how much. I sent mine to Chris at HEP to fix and re-clear so now it is perfect. Still haven't installed it....having too much fun playing it and taking it to shows! Bottom line is, if you have a blown out MM play field, either play field suppliers product will make your game look amazing!
