Me, too. Since I commute in the dark on the same bike I usually use for touring, I enjoy having the light available, but probably wouldn`t go that far if it weren`t also my comute beast. But since you asked...
Shimano 3N-71 and 3N-72 hubs, no complaints. Currently usng the Cyo IQ without nearfield, very nice. I hear the IQ Fly (less expensive than Cyo) is also an excellent value, but never used one myself.
