Alright from my experience, It is definately worth around 1.5-2.75K. 1.5 being lower end, and around 3K being the higher end (this is what i usually buy these quality picks for considering they are a common efficiency to acquire)
Umm, I know it isn't my position or anything, but please don't curse. And what Firebox said seems accurate. I've never actually purchased one, so I really wouldn't know.
