From what I have seen, $200? You might want to ask the folks on the Red Rifle forum.
I could have had one for $150. It was a sad day when I had to pass it up.
IMO they're worth less than a bucket of warm spit, YMMV.
But... but... they can use AK MAGS MAN!!!
Expect to pay 400-500 for a D model. The other SKS models are more reliable though.
