Stern is taking people for a ride at these new insane prices. Regardless of whether or not people think Stern is better then JJP or vice versa it's clear which company has the greater cost per game and it's JJP. A Stern LE and JJP LE are now basically the same price. The JJP LE comes with significantly more hardware in it from the old Bally / Williams style lock down bar mech, the traditional head lock, and especially far more hardware in the head of the cabinet compared to a Stern. Open the backbox of a Stern and you will see a couple small boards, open a JJP backbox and you will 5x the amount of hardware. There's other items as well including the metal leg protectors, the entire head being made out of wood, boards being full RGB, etc. I won't even touch the coding aspect which I think is higher at JJP compared to Stern.
Again none of what I said means one companies games are better or more fun then the other but it's clear which company is making more profit per game at these latest prices. Did Stern raise prices because material cost are up? Sure, a bit but the real reason for such a large price increase is that they believe there's enough people to continue buying games at the higher price point.
Perhaps JJP will now raise prices from $10,500 to $11,500 after seeing what Stern did, then Stern will do the same in a year. The price increase madness will likely continue.
