Thanks for all the answers so far.
In answer to questions:
- We all speak german, its the native language of the kids (3 & 13) but the older one started in a British school, and so I am reluctant to change that as the systems are very different.
- We used to live in Munich, so know full well about the expense of that option.
- Workwise its somewhat flexible though anywhere well connected to NRW is good as I work in IT/telco.
- My wife is not working at the moment though that might change if we move back.
