I'm in the other camp, though I'm only a user and not a collector. As a buyer, I prefer to have it freshly refurbished. I.e., given two listings of the same CRK, one with scratches and one just refurb'd and costing extra by whatever refurbishing it costed, I'll buy the latter.
I want my knives to have scratches put on by me. Other scratches are meaningless. I'm less likely to buy a CRK with lots of wear because I know I'll get it in, have to send it out again (to CRK to be refurb'd), and then go through that horrible, horrible wait for it to get back. Buying it already refurbished saves me time.
That said, since you can't de-refurbish it, you might as well list it as is, and then if it doesn't sell, send it in and list it again when it's back.
