Those shark/gator bite thingies are more expensive than the camlocks though, and are brass as opposed to stainless?
+1 on the camlocks, for what it's worth. I use 'em on mine, and love them.

I got mine from Proflowdynamics, but would recommend looking after HBT's own, and snagging from either Austin Homebrew, or Bargain Fittings:
