Some Norinco guns aren't allowed in the US, for example, the M14 which the previous poster mentioned. I forgot the actualy legal reasons, but they allow some. Most of the Norinco guns you will find in the US are SKS'. From my advice, Norinco's kind of suck. Sure, they are a great deal but you always pay for what you get when it comes to firearms(or just about anything). You can actually go and buy a -real- Tokarev for probably the same price you're going to pay for the Norinco clone.
I havn't heard much about the Norinco Tokarev or the fact that it's chambered in 9mm. A real Tokarev is usually chambered in 7.62x25, which people seem to love the round for the cost effeciency. A Tokarev can be filed as C&R weapon, if it's the real deal, and that just makes them even easier to come by. Take a look around at a few websites. I know a few that usually have them in stock, but I can't post them here because I think it's against rules. If you send me a email, I'll send you a reference for a few sites to check out.
All in all, I wouldn't go Norinco, but that's me.
