Quoted from Benepinballs:Jack himself has announced that if you are the original owner and bought your game from the JJP or an authorized distro, and you sell it within the 1 year warranty period, the warranty is void. Even if you have waited 3 years for your game and get it and decide you don't want it anymore.
That simple.
This is NOT true, spoke with JJP 2 days ago regarding this very topic and they claim that even after the 1 year they will take care of all known issues, WOZ light boards etc.
