I also need to point out that recording offline with any mic is not the same as using vox in AH online. Not even close.
This is a good point. The vox in AH is compressed heavily, which means no matter how high quality your mic is, its going to sound pretty much the same (i.e. crappy) for Aces High purposes. (Though with the latest version notes, there's some indication that Hitech may be adding a higher quality option in the future.) IMO, if your concern is AH/Vent/Teamspeak, there's absolutely no reason to spend for an expensive mic. You want one that will be "good enough" in fidelity, and won't break on you. The Logitech USB mic I quoted in my previous posts both meets both those requirements in spades and also costs ~$20, as requested by the O.P.
