If you're looking for a quality studio mic then I would first read some literature on microphones to find out the difference between the different types of condenser mics. But that woudl be what you want, a condenser mic. You're going to have to make sure you have a good sound card though, preferably one that has 1/4" inputs, you will also have to purchase an adapter cable for the mic so that it will go to 1/4". You might be able to find an adapter that goes to 1/8" but I'm not sure.
Some good microphone manufacturers are Shure, Neumann, Sennheiser, AKG and Audio-Technica. You can usually find good deals on Ebay and since mics are meant to last a long time you don't have to go with the latest and greatest.
