Used NOS, I get thats an oxymoron. I have a cyclone where someone dropped a NOS PF in awhile back but I'm thinking I want to get a CPR pf. This pf has mylar and only issues are one of the inserts has a blemish and there is a paint gouge in the drain lane. What's a fair price for this pf? And by fair price I mean get it out the door within 30 days.
