Anyone know where these can be had relatively reasonably? 20's or 30's either one. Thanks

I assume unconverted?

Yes. I don't really speak Saiga; don't own one and don't plan to, I'm just in the strange position of having one in my safe. My son's girlfriend is from out of state and currently lives on a college campus near us, so (since she can't keep her rifle at her on-campus apartment, and my son doesn't have a safe at his place) I'm letting her keep her saiga in one of my safes temporarily. Thing is, she only has one magazine for it, a ten-rounder, so I thought I'd see if I could find two or three higher-cap mags for her. If regular AK mags fit, I'd let her use some of mine, but they don't, so I just thought I'd see how expensive it would be to get her a couple.

Thermold AK mags will work in them if you file a bit off the back lug of the magazine so it will lock in at the mag catch on the rifle.  Or SGM (Surefire) has hi cap mags that will work.
