I have stated my opinions in other threads on Fenix vs. DiNotte. I have both, use both regularly, and like both. If I had to do it over again, I'd keep what I have: DiNotte on the bars, Fenix on the helmet.

This morning I did a 3.5 mile jog. I wear a NiteRider Digital Evolution at 15 watts on the head, with a Fenix in my hand to flash drivers, when not using it for that, I keep it on the road ahead. As many others have experienced, my NiteRider inexplicably turned off (this actually happened three times during this morning's run). This was not due to low battery, either, as it was fully charged when I left; when I got back I still had 3 of the 4 little green LED power level indicators still lit, indicating approx. 3/4 charge). I did not notice it at first because the Fenix overpowers the 15 watt halogen. I wouldn't even consider anything but a Fenix and/or DiNotte. Most Fenix and DiNotte owners will agree with me.

If you're on a tight budget, get one Fenix. If you can afford it get a DiNotte taillight. If you still have money left, get a DiNotte 200L headlight. I got my DiNottes (front and rear) on sale; total cost for both, plus the Fenix was approx. $260. They're worth every penny!
