I have the one from Lokar. Spiffy and pricely little bugger. One day I might get it out of the shrink wrap and put it on. My brother in law picked it up for me a while back and was going to put it on when he had my car, but later told me the car was quick enough and if he had installed it, I would probably just kill myself with the accelerator. So it is still in shrink wrap.
