SureFire headlamps?

Anybody have any experience with the SF Minimus headlamps? I got to mess around with one for a minute or two at Cabela’s awhile ago, and I like the way you can tilt the body within the frame. Also, do any other headlamps out there provide infinitely variable output via a physical knob/dial or the like (versus a ramping UI using a button)?

’danks guys!

I know the Icon Irix does the same type of thing for the UI, not as bright though. :(
