How about one of the Crown Dependencies of the UK... like the Isle of Man or the Channel Islands.

Both are natively English-speaking, have laws *based upon* but not direct copies of UK law. Personal taxes are lower than the UK, but the health care system is free at the point of delivery, like the NHS.

And it's quite convenient to get back to the UK to see your less adventurous relations. :)

The only down side is that at least the Isle of Man requires you to get a work permit for the first five years, and I think some of the Channel Islands still have minimum income/assets requirements for residency.

They're even nice places to live.
