Depends on what you want out of your flying, other alternatives are:-
Gliding - cheaper but time consuming
Microlights - cheaper, and some of the modern ones are VERY capable.
Homebuilt/share once yoou have your licence - keeps costs down but not sure of how this works in Germany.
I would say the Microlight route might be your best bet.
