Never buying NIB again. Stern Iron Maiden was my first and last.
Was pretty worried about getting a shit playfield going in due to all of the problems with Stern playfields, and sure enough, immediately after unboxing I noticed that my playfield was ribbed to all hell. It's laughably bad. Had to turn down the brightness on the backbox light just to try and hide it from my eyes while playing. Ugh.
Never again.
