I like the Astatic 636L mics in the mobile. I have 3 mobile radios, and 3 636L mics, they all work great! Loud and crisp, clean audio for a non-amplified noise cancelling mic.
If you're after a power mic, both mics that Mr. Clean mentioned would be good choices (Astatic Road Devil and D104-M6), along with an Astatic 575-M6, if you can find one.
It's really all about finding a mic that will match up with your voice, so if you have some extra coin, try a few different brands and have a couple of your buddies listen to you while trying mics to find the one that's right for you.
