You guys know the only reason these perfect mods cost so much is because of collectors like you raising the price by buying them for all your weird items that sit around in storage so they look more rare which then increases the cost of... you get it!
I'd have to agree exactly with Master, even if there are mods you're going to remove you're going to end up paying more for it because it have that 20/20 sundering (even though you're replacing it with a fiery bowstring ).
