CPR usually slow in answering emails. However CPR is the best solution by far compared to life before CPR. Before CPR I'd buy 2-3 project games of the same title to use the best PF, BG and plastics to make one nice one. Then sell the rest. Only PF options were NOS PF's. I bought a Xenon in 2000. Found a NOS PF in Germany on eBay with a scratch in front of a sling. Had it shipped to Ohio, touched up and cleared and then shipped to me. When I got it, it was warped 1" from corner to corner. Installed the side rails and put weights on it trying to level it. After 6 months it was still warped. Stuck it under my pool table in FI mode. I had way more in that PF than the $695 Xenon's CPR sold on their 1st run. I pulled it out many years later and it was close to level. So I installed it and now it's perfect.
Had I know I could buy a CPR in couple years before that adventure, of course I would have waited. But life before CPR sucked.
