Here are some prices: All are Arena so there are probably other prices on the tribune (sometimes more expensive, somtimes cheaper)

Amsterdam 41 Euros
Munich 55,50 Euros
Zurich 80 Franken (they don#t have Euros)
Bremen 53 Euros

That's all I know at the moment. I don't find it anymore but Mannheim should be the most expensive German concert so it costs more than Munich.
