I would most likely be interested in a white wood starter Playfield and templates/jigs - preferably router jigs for most/all standard inserts.
I've got a lot of parts already for a build, got the basics designed in Virtual Pinball, have a a p3-roc and most boards I'd need, etc, but I've stalled out on taking the next step.
I've been debating learning CAD and getting a Bob's CNC setup capable of cutting a playfield and convert my VP table into something usable to do the playfield - but that has a number of challenges and $$ outlay too. My initial plan had been to do it manually and make my own router jigs for inserts - a starter kit in that direction seems ideal...
