If you want cheap and high-quality, then the Shure SM-58 is for you. It's the industry standard mic for performance work, and it's actually suprisingly good in studio production. I use them for voiceover work all the time, and they're clean, crisp, and deliver a true sound. You do have to be careful, as they are an omnidirectional mic and they do pick up everything, and I mean EVERYTHING. Make sure you don't have anything going on in the background of your studio, but hopefully you're already taking that precaution.
