John,

I don't know the build costs of this particular one, but the way things are done here certainly an order of magnitude less than the same thing built in Europe or OZ!

It's operated by Cottars Safaris in Kenya, http://www.cottars.com/home.php, and was built by a Sikh an a Brit fellow. I saw the build pictures in the Sikh's office, lots of good ideas in there.
