I had the opportunity to use a Leupold VX 3 while in Africa 2 years ago. It was a fine scope.
Had the opportunity during the 2012 NRA convention to fondle several Zeiss scopes.
I bought and absolutely love my Minox scope in 3X9 - 40 mm. It is much clearer than the Zeiss and IMO very equivalent to the VX3 for much less money
