Denmark.

I wasn't particularly looking to move here, though it was a country I'd thought about. Then someone forwarded a job advert to me, and I ended up with an offer I couldn't refuse :-)

Anywhere in the EU is easy to move to, and easy to move away from if you don't like it. The big differences are probably the ease of getting a job, speaking the language (or not needing to) and meeting local people.
