Botswana formerly Bechuanaland, Botswana became independent (within the British Commonwealth) in 1966 and is often held up as "the way to go" for new nations.
Postscript: My boss and his daughter went to Botswana in 2003, and the last thing he told me before he left was, "If DHL shows up with a box of lion shit, sign for it - it'll be me!"
