@JO: Lucky you, recently spent 4 weeks around in Germany, typical landing fees are i.e. between 12€ and 18€ for a <1.2to and a usual mid-size GA field, very few cheaper - didn't encounter any less 8€, lots more expensive - everything up to 35€ for <1.2to is thought normal (some strange lateron bills from german DFS included).
@tomboo: what is a "cheaper" hire? A typical C172SP goes for 260 Euros/h ...
