That's a fair amount of range between those two replies... anybody else? or more explanation of why you think what you think?

As Malice said, essentially clean 15-22 IDS goes for 15-20ish, the 15^50 would (I would certainly think, anyway) push it up some, as would the near-perfect enchant mod. What all that adds up to, though, I'm not sure.
