July 2007. When I arrived at the Fankfurt airport, I was very anxious to see Germany so right away, I bought a day-pass for 13.20EU. The trains and busses there stop at the airport and are very accessible. Be careful not to take the fast train (white, bullet type). The fare there is double the ordinary train's fare (red, other type). If you're caught with a 'red' ticket on a 'white' train, you'd be charged an extra full fare.
