Don't get me wrong, I ordered some Boulder air lift mag. I prefer GI mags. I've only in the last year bought a few Pmags. I am probably a Magpul fanboy but I don't get the wild popularity of the Pmags. For poly mags I think the Lancer L5s are a little better. I'm loving this, as I've been getting the aluminum mags for almost nothing. I'm curious to see how a 40 year old plastic mag is going to look. My 40 year alloys could pass for half there age. This mag thing id gonna settle down, and used pmags will be 10 bucks.
