I just bought a Ruger hi-cap mag. I haven't had a chance to shoot it yet, but it has steel lips and seems solid. When I get a chance to test fire it I'll give a report. I think is was about $25 at Gander, but I bought it with a bunch of other stuff during their sale a few weeks back and don't remember exactly. I have an old ramline 20 rounder that I never have had any problems with, and the Ruger seems to be better made. Report to follow.
