Voice repertoire

For those who don't know, I'm a voice impersonator. I really like what I do, I enjoy it. Lately I've been looking for a good quality microphone that doesn't sound fuzzy, and is within budget. Somewhere in between I thought I should take the flash skills I have so far and use them to make a soundboard of my voices thus far. (and only the good ones, and not the ones that are names of friends' custom games) Mario is considered my best, though I hope one day to improve on him a little more, I don't think he's as good as I can make him. I also have Sonic and The Cheat.
