Bit late to this and sorry if its been mentioned but DuoLingo is fun. You won't exactly become fluent (more like passable holiday German) but its a great start.
EDIT: Just noticed its already been mentioned. And rubbished. Oh well. Works for me. Just messing about.
I want to learn to speak German.
Recommendations for ways to learn if I have one evening a week to spare for attending a course/class?
