Not all SKS's are created equal! I suggest you do your homework and read the FAQ stickies under Red Rifles, particularly Curtton's excellent contributions. Then, physically inspect one from a local seller, or order one from a reputable CGN dealer.
Spend $50 to $100 more and get a beauty.
I suggest weimajack, as his are as good as they get. If you want to bubba the sucker, then probably any SKS will do.
BTW, accuracy varies with each SKS, but most will do 4 to 6 inch groups at 100 metres with the iron sights using the surplus Czech ammo if you do your part. I have two that consistently do 3 inches or less. They are also nice looking SKS's -- but frankenpinned. I solved that problem by sending them to Murdoc to be parkerized and arma-coated.
