After watching George’s explanation, can better appreciate Stern’s efficiency over other manufacturers in reducing wire mess complexity. Other manufacturers show underside of their machines, with wire running all over the place, it may seem they put a lot more in their games. But reality is more parts and wire are needed because their systems are quite inefficient. Consumer has to pay for all those extra man hours and parts. Hence the reason other manufacturers charge so much more for their pinball machines. Yet the unsuspecting public say, look at how much more they put in their machines over a Stern. In addition, all the extra wire and parts cause heavier weight issues as well. More parts mean larger maintence issues in the future. Inefficient systems have a domino effect on everything.
