Well typicly SOF goes for more than f14 seems the average price has gone up to to about $1500 for a f14 now fro $500-$1200 2 years ago lets say so taking this into consideration and the fact a big part of this titles production went overseas I would say $1400 is a decent price nowdays.
If you want a perfect SOF be willing to dish out $2k or more easy this one the mini pf isnt trashed and even with slight wear even the insert artwork dont seem damaged hardly so what are you waiting for? this should be a $2k game as it sits
