I ended up with a Princeton Tec Byte headlamp after learning about tilting headlamps. This thing is amazing. Just what I wanted. I can see very well where I step and it's pitch dark outside of a nice, focused beam.
Awesome when people find what's right for them, and things really work out.
Partly out of curiousity; Did you get a backup light as well, such as a keychain light? I can't recommend having a backup highly enough.
The Lumintop Tool AAA (already mentioned previously in this thread) is a good option. I EDC one, but I'm probably replacing it with a EagleTac D25AAA.
If you do decide to get one, it's worth giving some thought into emitter type. Nichia (available for either of those I think) has *much* nicer colour-rendering, and is overall a great choice, but others will give you about twice the amount of light for the same battery life.
