You may be thinking of the velo orange hub that has a star wheel to lessen drag when lights are not needed.
The Shimano works great. I know it has some drag, but I really can't feel it. At higher speeds (>25mph) you can feel a very slight high frequency buzz through the bars when the light is on. I find myself using my lights more often than if they were battery powered, for instance on overcast days or when it is rainy.
I build my own wheels, so it was less of an expense for me, but since I was converting from 27" to 700C for more clearance, the dyno hub was a no brainer.
