PC on Sundering Amber Longbow of Fortitude

I would really appreciate if someone could help pricing this:

Sundering Amber Longbow of Fortitude
Piercing Damage 15-28 (Req. 9 Marksmanship)
Damage +15% (while in a stance)
Armor penetration +20% (Chance: 19%)
Health +30

Thanks in advance.

5k~, but I would wait for NF and then salvage +30hp mod from it.
