Petzl Zipka has served me well for a number of years. The Petzl e+Lite works, but isn't very bright. (Of course, neither am I.) The little retractable cords always intrigued me, too - no stupid webbing band to deal with. The Zipka was bright, but you couldn't tilt it to aim it. The e+Lite could be tilted to aim, but was pretty dim.

Recently, I picked up a BD Ion - simple, red and white lights, with a tillable lamp, and a webbing band that is fairly narrow. I haven't had a chance to try it out yet.

For some reason, I keep coming back to Petzl.
