Small Scale Military Headquarters

I have seen some comments that these are going for some fairly substantial prices on Ebay lately.
I got mine about 3 years ago.I have one Su 27,and two Su33's.
The quality is not bad,and at the time Gaincorp made the best quality Su27 around.
Does anyone have any idea of what they are going for these days?Not interested in selling,but it is always nice if your models are worth substantially more than when you bought them.

It does seem that there is an Su34 on Ebay right now.This is the twin seat,side by side version.
It has a starting bid of well over $200US.Chinese Su27 for about $50US.
No Russian Su27,or Su33 listed.
Looking at a couple of other sites,it seems that the Su34 was a limited run,and hard to come by now.
Starting at $200+.Yikes.
Anybody have info on the Russian Su27,and Su33.
