Well, not really, unless it turns you on. Looking at the practical side of it, what benefits does a fully CNC brake give over a normal one? Certainly not durability from what I've seen. I've got a Maggie with Coustsinks, my friend has a Dengura. Out of the two, my brake works far better, and I've only spent ~55 pounds on a new brake, brake pads and clamps. The Dengura is about 100, so not only do you get a better brake that won't start leaking after a week, but save enough to buy a BB7 or something. If deng wasn't so thick as to introduce these brakes and then say "well sorry but these brakes are full of aluminum leftovers in the system that scratch the pistons and cause the brake to leak" i'd probably justify getting one of these. But it's just another overpriced deng disaster like freewheels and freehubs.
