A converted Saiga 308 with ten magazines will cost more than a Century FAL with ten magazines. A lot more.
I have a Cetme, (with ACE side Folder) an FAL, an M14, and a Saiga 308. If I could keep only one, it would probably be the Saiga, if and only if I had ten hi-cap mags, which I do not. My second choice would be the CETME if and only if I had a functional scope mount, which I do not. The M14 is just too damn big and clumsy. That leaves the FAL, for now. It is accurate, reliable, and fast handling (despite it's length)
