They were pretty scarce up until the Sportsmans Guide mag lottery, & a few escaped into public hands by the CDNN "used combloc" mag sales.
Right now, I'd say there's more of those than AK mag collectors.
In the past(pre-SG mag lotto), I'd sold them at $35.00 each. In the past year, I've quietly bought a few nice ones at $12-$15.00 for future sales.
Definately money in the bank...... Especially once the real story on these comes out(the Chinese aren't talking & a few folks have pointed the finger at Albania). No one really knows anything definate about them.
