I know everyone here is "buy buy buy!" but I prefer my Norinco chinese SKS to my '54 russian.
Here's why.
Although the russian has a better quality bolt and internals, the chinese was easier to clean initially by far. The Russian stock was perimiated to the core with cosmoline, no amount of steaming and heating gets it out. The chinese variant has a more mild oil, to which cleaning the stock only took soap and water. The russian took a lot of boiling water + dish soap + simple green to get all the thick cosmo out.
Both have about the same tolerances when it's cycling, and both need a trigger job to remove the 12+ lb trigger pull.
The chinese has 'looser' components. For example the release for the magazine is much easier to open.
The chinese cost $150 + tx and the russian cost $220 plus tax. Both have matching serials all around. They both have chrome lined barrels, identical safety levers and both have the same accuracy at 50 and 100 yards for what I can shoot.
I bought the russian first, and it's still a great rifle - but the chinese is all I needed. I don't regret buying the russian, as it's a great rifle, but it'll probably hit the EE soon enough.
