Don't get one at all... better yet.
14% is very high, but that may just be due to your age/lack of true credit history. You are a student, right? Most student I see have higher credit percentage rates than non students.
The lower perecentage rates are usually offered for more established people.
I agree to paying 0 every time, and either paying the bill when it comes. Or just paying cash when you want to spend it...
