I carry a Surefire E2L Outdoorsman every day. I would be lost without it. It has a low and high setting which I find perfect, and a clip so I can attach it to my hat. What surprised me, was their 123A batteries lasted for 9 months before I need to change them because the high beam wasn't working any more. I was going through AAs in my Mini Mag every other week, and a bulb every month. The Surefire has definitely been worth the price, and I love the push button.
