SAIGA rifles are really nice guns for the price IMHO. A friend of mine just picked up a SAIGA 20GA and I must say the build quality was better than I was expecting. The only draw back to the SAIGA rifles is the crappy trigger system.
I have owned an Yugo SKS before that left a bad taste in my mouth for SKS's, but I think it was more my fault for being a newb at the time and not knowing what to look for in a restoration gun.
I guess it all depends on what you are going to be using this rifle for. If you plan to just plink all day long, varmit hunt, or punch paper why not consider a SAIGA in .223 ? It's almost the same price ammo with less kick, and better ammo selection.
I would also have to agree with the people above me, almost any russian gun chambered in 7.62x39 is going to be a deacent truck gun. As other have mentioned before me the 7.62x39 is very similar to a 30-30, wich means it's going to drop a deer,person, or bear in their tracks at any distance under 100 yards. The only draw back is that while 7.62 does not kick hard at all compaired to a lot of rounds, it still kicks a good bit more than a .223 and it costs the same.
Either way you go, Unissued SKS, or SAIGA you are probably going to have a lot of fun with the gun.
