The art can be in photoshop, AI, Corel, etc. at 300 dpi or better. The cad files could be done here comparing the art package with a worn out playfield. The main thing I need is a good art package, in return the person would get 2 playfields (maybe more).
I talked briefly with Gary Stern at Texas Pinball Festival, about inkiing & clearing playfields which they have had problems doing. Haven't heard from him since, & I have learned from my mistakes over the first 2 years. Also people have destroyed $50k inkheads, so you need to be carefull!
