Any recommendations on a good software program to record vocals and instrumentals? - record software demo

I am a song writer, and I would like to include some demos of my songs. I'm on a tight budget, so I'm looking for something that will not cost a fortune. I must be able to record vocals, instrumental music. I want to be able to mix w / this software, but not absolutely necessary.
