i rode the prototype of that Muddy Fox,awful ride. We were trying to kill it,jumping down stairs and stuff but it took everything we threw at it,to be fair.
I once touched a $70.000,= frame of America (build by Brush-Wellman), but can't find any photo of the Beryllium frame with alu lugs... I know they are über rare with (as I reckon) only 7 ever made...
The chainset on that bike was incredibly expensive if I remember right, hollow titanium crank arms or something. I always wanted one, but probably only because it was so expensive.
