How much would you add to value of a Diner pin just because of the diamond plated playfield? And any opinions of value for a nice diner with some minor insert wear? Thanks Don

Thanks for the responses. So the diamond plating is just a clear coat and by itself adds no or no value? I am looking to buy a Diner, seller wants $2200 and made a big deal of the diamond plate. Don

Thanks to all.
I've read the referenced WW playfield discussion and all your responses. Agree with johnwartjr's arguement about the whites. My conclusion from these discussions is that only if playfield is in good condition is it worth a premium of $200-$400. I am supposed to lay eyes on and possibly buy this machine this weekend. Will check the up/down ramp. Are there any other game specific trouble spots or items to check??
Thanks again, Don
