I've got two Russian refurbs and one Norinco; love em all.
Let me be very clear in saying that there is absolutely nothing wrong with the Chinese/Norincos, in any way. Many SKSers believe they are the best shooters.
You will pay more for Russians simply because there are less of them, and they have developed a --cult collector? fan base. Maybe I'm one of em.
All have chrome lined barrels except the Yugos, and you will find some guys that say that they have more accuracy potential than chrome lined.
This is my newest Russian refurb, a Tula 1954, unfired(since rearsenal), in the box with all accessories, for $300. Good luck finding a similar deal. Keep in mind that most of these refurbs are painted rifles, and many folks prefer the nice blue job that is found on unrefurbished guns; chinese, romeys, yugos, etc.
Here is my Norinco that I have been Bubbafying for awhile now. I've been having a ton of fun with the project, and it's a great shooter; as a matter of fact I hardly shoot the others.
MOST SKS's are peachy little rifles that you will fall in love with. and worrying about fifty or even a hundred bucks one way or another won't matter to you after you are enjoying it. Come over to SURVIVORS SKS BOARDS and poke around if ya haven't yet. jd
