Vampire Gaze HC PC Value

I've been struggling to find a good replacement for the Tal Rasha's Mask on my hardcore zealot. I actually do have an Andariel's Visage, but I have more use for the life, dual leech and resistances on the Mask. Yeah I have a couple of Guillame's Faces but I have Gore Rider Boots for CB so I still need the defensive stats more.

Conclusion - I'm getting the Vampire Gaze and I'm putting runes in it for resistances. When I've been looking around to buy one, people keep asking way higher than the price estimate I get when I look at D2JSP (I don't shop there but I use it for price comparison). Over on that site, an average Vampire Gaze goes for 20 fg, or roughly a Pul or less. On Battle Net I have had multiple people turn down offers of 2 or 3 Pul's. One guy wanted a Vex, although that was for a perfect one.

What the hell are they worth? What should I pay for an average one?

Well I ended up getting a lower tier one for Pul and Lem.

I feel that in game prices have been inflated of lately, not to mention the 'smart guys' that make outrageous offers (I've seen a Pul 4 Lo game not too long ago)
