I've had an old Inova X1 for several years, it has a single mode, and optic instead of a reflector. I didn't know they made 2 mode or reflectored X1's now. I love my X1. As tlyon said, it was cheap enough that I'm not worried about roughing it up. It has an extremely tight, even beam (it has the optic, as I said). There is no hotspot, just an even circle. It has a green LED, and because the optic keeps the beam so tight, it has very impressive throw even though it has a very small head.
The best aspect of this light is that it's small and uses very little power, but still puts out impressive throw (the optic version at least), and it's cheap.
