If I was buying a game for 11 grand I would expect near perfection.
GNR has known, and serious playfield chipping pooling, and delamination artwork issues.
I personally would not take the chance on GNR right now.
JJP has not publicly addressed the issue.
Mirco the playfield manufacturer says there is NO problem at all.
So I would stay away.
Also I would never pay more than $9500 for any pin, ever manufactured.
I would buy 3 or 4 gorgeous 1979-1982 solid states, for that 11 grand.
But that's just me.
Good luck.
