Think you'll be hard pressed to find collector quality personally. These were so popular I would bet many made it on site! I own what I think is an amazing example but having wear of about a 5c coin around one flipper and 2c around the other can not be classified as CQ. It is perfect in every other way and plays just as good.
I would almost call it CQ...but others won't.
Either way, good luck with search, hope you find one. It's a cool game and the colour DMD looks like it was always meant to be!!
