Quoted from Betelgeuse:Stern has had playfield issues for a lot longer than JJP and they dragged it out forever. They STILL have problems like warping and guide rails tearing the clearcoat. They have put a band-aid on a bullet hole by removing the artwork from around posts, but I don't really think they are out of the woods yet. Things just look better for them at the moment because JJP is having bigger problems on a popular title.
True, but Stern stands behind his products and in case of playfield warped, they replace it. 2 friends had this kind of issue on 2 different games and Stern did it right.
