The place I've heard mentioned is Munster. It's been about a year since I was last there but had no problems at the time myself.
I've been asked for my certificate of insurance at Muenster in previous years, no checks in three visits this year, despite the scaremongering in Pilot. Just have the required paperwork , anyway! At EUR 18 landing fee (plus EUR 10 nav, no handling) for a sub-2000 kg aircraft at a major international airport, I think the value is well worth it.
