I have seen HOU that are beat to crap too. As with anything it all depends on condition. But $2000 sounds ridiculously low for FGY unless its beat to hell and they announce a vault edition (hopefully they can still get the figures ala LOTR). Correct me if I am wrong but not too many were made. This sounds like some get a data established to point to a low ball offer. I don't have a bone in this since my NIB/HOU FGY is never leaving (I buy keepers to hold). Funniest pin ever made. Unique layout and great rules. One of the better toys in a pin.
If your dealing with an op I assume they know the market better than you. Before you consider playing the I want NIB card make sure you want what your threatening since it might cost you long term with this Op (and his friends). Best to make things win/win. Good Luck!
