Ben heck is exploring the idea of making a small pinballl kit and taking it to market if it's feasible. There's a thread on here about it. Just search for teensy pin.

This kit would not be a product for stern. It would be a great product for mission pinball or fast pinball; their already a maker community.

E.g.
Provide a kit that gives all common mechs, switches, and lights ect for a game "in the spirit of" a stern title. Then the customer could find a Playfield to install it all on, or make their own Playfield. .....imagine a kit with all the bits to make a tron machine, just without any of the IP infringing items. Those would be bought from Marco or stern.
