I have owned yugos and norincos, and i havn't noticed much of a difference in performance at all (thats with well made norincos mind you... if you know what to look for when you buy norinco you can get a good quality gun).
I dont like the wood stocks on either of them though; the butts aer just way too short, and the grip is uncomfortable; I always put aftermarket stocks o mine, the dragonov made buy choate is probly my favorite so far, the para isn't bad either, and it allows you take out the trigger assembly without having to unscrew teh pistol grip (on the choate the grip fits snuggly against the rear of the trigger guard). the fibre force is a nice one too.
As for re-finishing wood stocks, my sks's are carry guns, while I do take good care of them, they do get beat up and i simply dont concern too much about cosmetics on carry guns. I like them to look mean and ugly, but work like a dream.
when it comes to ordering from Milarm, I've had both very good and very bad experiences with them. one thing about them is it is by far best to actually go to the store (I realize it may not be possible for those of you across canada) you just can't personaly pick and choose for quality, and it being largly surplus, quality varies greatly from gun to gun. I once bought 12 SKS's from them as well as a few thousand rounds of ammo (it was a bulk buy between me and a couple friends) They dropped their prices through the floor and gave me all kinds of deals, it was great dealing with them. (I was at teh store to buy them)
on a different occasion, however, I ordered an 8mm mauser from them and it took 5 months of @$#king around to get it mailed to me
