I've got two headlamps and one Surefire flash light that I use regularly - one is a Black Diamond Icon, the other is a heavy-duty Petzl (rechargeable), I forget the model. All three lights have worked well. I've used lithium AAs with the Icon and the Surefire flashlight, w/o a problem, including during winter volunteer weeks on the summit.
Surefire Saint Minimus is the headlamp for me. Lithium 123 batteries can be bought online for $1 each.
Petzl make a number of high quality headlamps but if you want something low-cost, that is also very good ... the Princeton Tech Fuel 4 headlamp.
I have owned & used a number of headlamps in the past, from the Petzl Zoom, the new Myo's with belt pack (which are super cool) but considering overall weight, weather resistance, brightness and finally cost ... it's tough to beat the Fuel 4.
My appologies if this has already been mentioned.
