I have Chip McCormick Customs.
I like the ones with the guy's name on it. and don't mind paying a little more. I only have four; all for SD carry purposes. I figure he has a lot to lose if any get out there that are crappy.
I once asked the man that makes my flute headjoints if he sells any 'seconds'. He recoiled in horror and said, "Do you know what would happen to my business if I let a sub-par headjoint get out there with my name on it?" It made a lot of sense to me, so I use Chip McCormick. Also, that's all the ex-Marine gun shop owner I patronize sells. He knows his stuff too!
I find people that know much more than I do about a subject, and follow their advice. It saves me a lot of time, and allows me to do other things. YMMV.
