Norincos are fine, though it's illegal to install a bayonet on it. Other models are classified as Curio and Relic, and are allowed to have certain features if they have to do with the classic configuration. Romanians, Russians, Yugos, and Albanians can have bayo lug, Yugo 59/66 can keep its grenade launcher too.
Far as I know, Romanians are fine. Depends a lot on what's available to you, as most non-Yugos will probably have been pre-owned. That means there may be choices of accessories and configurations. Watch out, as a lot of people can configure an SKS illegally without realizing it. If you're not sure, ask here.
And yes, $200 is a fair price for an SKS in decent condition. But it's a mixed bag.
