I have a WASR-10 from Century. It is a good, solid, reliable, Rumanian built AK-47. I love mine. I live on a patch of sand between the ocean and The Great Dismal Swamp, so mine has been thoroughly tested! We sell a ton of these for $400 a piece, so $450 seems a bit high. None in recent months have had even a hint of sight or gas tube cant.
I also have a Century GP75 AK-47. They have new barrels by Green Mountain of New Hampshire, who have been making high quality rifle barrels for ages. The receivers are by DC Industries out of South Dakota, and are about the best AK receivers ever made anywhere ever. The gas pistons and the slant-cut muzzle brakes are new, probably American. The Parkerizing is very nice, and it is uniform on all parts. The furniture is new American black synthetic by Tapco, same with the magazines, and the fire control group is Tapco G-2s.
What parts are original Soviet I can not tell. It all seems brand new, even the cleaning rod and sights. These are amazingly accurate guns, way better than you would ever expect. We usually sell them for a bit less than $450.
If this sounds like a commercial for Century, that is not my intent. When they make an 'Oops', and they have more than once in the past, I am not shy about saying so. However, the stuff of theirs I've seen recently is darn good.
Ammo in 7.62x39 is generally less expensive than .223/5.56. This is partly because an AK-47 will eat any cheap ammo you might find, while an AR will often choke on the non-brass cheap stuff.
In any case, if you want an AK, do it soon. Prices are way down from the panic days, but the supply of them can not last forever, and when it begins to dry up, the prices will climb.
