Most of the early buyers of new machines don't care (much) about the playfield quality.
It's going to arcades and pinball addicts (like me).
I just want to play a new machine asap and that's it.
For me it's not some holy grail to cherish my whole life.
As long as the problems don't affect the game play, there is no problem.
If you 're not like that, don't buy NIB, wait till someone sells theirs and go check the machine (and rub that precious shooter lane).
