Whatever you do, make sure if you buy one that the backglass is decent. I bought THE last one Mayfair had...odds are 1 in a TRILLION you'll find another either NOS or in excellent shape.
Also make sure that the sling and mid target plastics aren't busted. I bought their last NOS set too...probably just as poor odds at finding more, they are busted on alot of machines.
If you have the means of printing and adhering them to clear plastic, you could always make your own, and I scanned the entire NOS set including key fob.
If you do get one, likely the arrow decal on the Robocop entry at the end of the ramp is faded real bad, a local collector printed me up a few on vinyl, just ask and I'll send you one once you have the pin.
