personally, i'd salvage the mods, since they'll probably be easier to sell separately. axe might get 2k or so clean if you can find a buyer, but they're so common i'd just merch it after ripping the mods
EDIT: First of all, read the forum rules. You can't post in your own thread until 24 hours after your last post. You can always edit your posts with the Edit button to add questions and whatnot.
Since the skin is desirable and the mods are good, you might get 10k for it. I tend to agree though, salvage and sell the mods will make for a quicker sale.
