Sorry, the threaded barrels are indicative of a higher-quality (or at least more costly to manufacture) gun, and there's a certain clout that comes with that. I would personally never buy a pinned-barrel SKS unless it was a serious bargain - like the major hurtin' unit that recently dropped into my lap for almost free.
Incidentally, the biggest issue with this gun is that the barrel pin broke
, almost ejecting the barrel from the receiver during live fire. That can't happen to a threaded barrel.
I've also heard that the threaded guns tend to be more accurate - and while there are good reasons to believe it could be true, I've never seen any actual evidence for it.
