So, if I may recommend something, I'd like to suggest the spark SD6-500CW.
Looks like a nice light. The thing is, I work for an outdoor retailer and that headlamp is significantly more expensive than what I paid for the Surefire. My needs as a casual user (backpacking, night running, dog walking) are also less demanding than somebody who might be using the light professionally. I wouldn't, however, recommend paying full price for one of the Surefire Minimus lights. It's a good light, but not great. Especially not for the price.
