This is sweet. If you get sick of a game, you sell the art work and playfield to someone else and pop in a new game. The only problem I see with it is lack of titles. If Heighway can produce 2 or 3 titles a year at a cost of $4000 then the pinball revolution will have begun. For the cost I would buy one of these and I don't see myself buying a NIB Stern any time soon.
