Extremely expensive but certainly if you can swing it well worth it as it does stop better than other calipers I have tried and they look way cooler too.
I saw them on a bike that visited the LBS; I studied them for several minutes, grokking the linkage. I never imagined the price, figuring perhaps $100 per caliper.
