Norinco SKS's were new manufacture items made for the US market. There are VERY few genuine type 56 carbines in the US. Most are probably war souveniers from Vietnam and will generally look like war souveniers and bring a premium price ($1000 or more). I do not believe any more SKS's from any country are currently imported so it is a supply and demand thing. The $75 Norinco from 20 years ago is now selling for $300+.
The Yugos are the only ones you will find that are genuine Mil-Surp items. They were issue items for many years and then moth balled to be later exported to an eager US market. Some are great little rifles and some are shot out, corroded, unreliable junk.
In life, strive to take the high road....It offers a better field of fire.
