I think the HP set will go for around 3000, as others have said. I'm not even going to try, because there's others here that are going to in more than I'm willing to. I agree that those posters will never be worth that kind of money, and while I've been known to throw some big money around for a rarity, that's way out of my league on this set.
So, have fun boys! I've got the popcorn ready!
