I own TSPP
I think $4K is just too damn much for this game
I'm not sure what I'd offer because I'd just wait for a HUO one to roll my way at a similar price.
Whatever you pay for it here's some advice. Remove the I&S protector, mask the top of it off with tape & then spray paint the other side bright yellow (the part that faces the PF). Remove tape & reapply I&S protector. Now shit will look bright yellow & clean!
In my opinion TSPP is the greatest game ever made. Get one!
