I just can't see any collector interest for an SKS of any type, but I get your point.
That said, I bought an SKS in the early 90s when they could be had for 90 bucks (about what I paid). It was a Chinese one but I swear I think it was brand new. No bayonet because of Cliknton's policies. I'll say those, the SKS is a damn sight more rifle than it is given credit for. I never worked with it that much, but it cycled and shot everything I handloaded for it way better than I'd have thought for something that crude and short. I even went so far as to try to see where the unreliability with handloads would start and can tell you, one can grossly underload, way below book minimum, before one will start to even stutter a little. The things are reliable to a fault and at least as accurate as I can shoot open sights.
