Seriously. Every time even a playfield is released for older games people complain. A color is wrong or a line is not in the same place.
I think the same thing that almost always happens will. The people spending the $8K will defend it forever (or until sold). The people who can't justify the expense will say they have always hated it anyway and make fun of every problem that pops up.
The only happy people will be the ones who actually play pinball since now more will be available to play. There just seems to be less of them these days.
