PC +10 vs. Tengu r9 Strength Shield

Hello,
I would like a bit of help PCing my:
r9 Strength, +10 vs. Tengu, +43 Stance shield.
It has the defender skin and is gold.

I have a buyer interested, we're just trying to work out what a fair price would be, considering vs. Tengu has been popular with feather farmers. Any ideas are welcome!
Cheers,
Sola

Bump! Any one have a good guess?

And bump again. No one has any ideas?

15-30K is a good price range just what you and the buyer can agree about
