Which magazines for an SA M1A?

Hi,

which brand of magazines do you recommend for use in a Springfield Armory M1A Loaded?

I've really never paid much attention to specific makers, as long as they're USGI mags. Haven't really kept up with the current mfg, aside from SAInc's. Their mags seem a bit roughly finished, but otherwise servicable. Checkmate seems to have a good reputation. The old Thermold polymer M14 mags have never worked all that well for me.

I use either USGI or the Checkmate CMI (stated to be current USGI contract). Both work great.
44mag.com has regular deals on the CMI mags. I have only used 20rd mags not the 30 so can't speak to that.
