PC: Gold req. 8 Bow

Hi, I would like a price check on the following bow:

Vampiric Flatbow of Defense
Piercing Dmg: 15-28 (req. 8 Marksmanship)
Damage +19% (while Health is below 50%)
Life stealing: 5
Health regeneraion -1
Armor +5



Anyone know how much this is worth/ interested in buying it? Thanks.

*good morning bump*

Any thoughts? Should I risk it for the 5:1 life steal..? The rest seems pretty good too I think.
