I bought a Smith & Wesson for my BOB a few months ago and LOVE it!!
It's very bright, and the battery consumption is decent too. I use Duracell process batteries and get quite a bit of run time.
The thing is rugged, bright, and has a great price as well. I know a few others that have bought this light and have been happy with the purchase as well.
It also comes with a nylon pouch to carry it in. There's even a place for a couple extra batteries! I wrote a review on it, check it out:

Great buy!
