PC on 3 skillmods please

I got 3 mods with +1 to skills, and like to know what approx. to charge for them

A: +1 swordmanship (20% chance)
B: +1 Deathmagic (19% chance)
C: +1 Domination (19% chance)

Thanks in advance

Anyone got a clue on one or all three of these mods?

a. 5-10k <<<not rare
b. 20-30k
c. 15-20k

Thanks, was hoping for more for the swordman ship
Anyone else?

hopefully this helps...taken from the weapon mod price guide

Hard to price items: Very specific!
20% Fire supposedly 100k
20% Death supposedly 75-100k
20% Domination supposedly 50-70k
20% Deathbane supposedly 60k average
All the +1 to skill mods
All the %damage vs. monster types

Yeah I saw that, and of course I checked the weaponsmod guidelines first. But it doesn't say how much of a difference the prices are between 20% chance death and domination and 19%.
