Personally, I would want to see them both in person before making a decision. If you already have the pin and are replacing the playfield then there are problems with either direction. For me, I'd prefer the CPR Gold route and deal with those potential issues rather than deal with all the problems that go along with a 40 year old playfield that has never been serviced. But, I buy my machines to play them. If you are a collector who is interested in the "vintage" value of a pinball machine, then I suppose a NOS playfield seems like it would be more valuable. It sounds like you are simply comparing two pins that are both already in great playable condition. If the "all-original" isn't a must have for you, then it kind of seems like sixes to me. All other things being equal, I'd probably go for the CPR Gold option. I have only ever had one of those, but it was awesome. Good Luck!
