The Century site has the Yugo M70 w/bolt hold open for 16 something right now too. I'd run with those if you need some.
Not that much difference price wise. If I didn't already have a ton of mags already I'd get some more.
Great price if there close to milspec. I'm at around 34 of the steel and bought 16 of the Tapco a few years ago when Obama became gun salesman of the year.
