I also have Pro Tools, I do not find it as user friendly. But, I know people who love it. In producers message board it is very popular. I intend on learning it, but I have been pumping out work in Audition for my final project, hopefully once I am finished school I will update this section with a more insightful view of Pro Tools.

Garageband is what I learned to produce on. This is what I learned on before radio school. It was a good way to learn, just fooling around on my Mac. But, it really doesn't produce the best audio. It is worth it to make the investment. If you are a radio student, your school may have a license key you can buy to save hundred of dollars. I recommend investing while you are at school, many students leave school without it (relying on an employer buying the product for them) and have to pay the full price for the software once in industry.
