I got 200 dollars to spend on a microphone, and I want to know what is the best microphone to record with. Also, I want to know what's the best way to make a home-recording studio?

My cieling is about 12-13 feet high and I have to closets in my room. Also, my room is not exactly sealed off...one wall is about 8 1/2 feet high and their is a gap between it that leads into the next room, if you feel what I'm saying.

So help me out, I'd appreciate it.
