It really is entertaining to see this "dimplegate" paranoia strike like it has here on Pinside lately.
I can only assume that it's due to the bad playfields that have gone out (with the bad ghosting and clearcoat disintegrating on some of them), so everyone is convinced that the dimpling isn't normal either.
Quoted from CrazyLevi:
You'd have to be insane to buy a new Stern these days, unless you are sure it's a keeper for you. Not because of any playfield issues, but because rampant paranoia is going to make them almost impossible to sell to anybody here for a long time.
Funny, I had a friend text me virtually the exact same thing!
