I just ordered two of the Black Diamond Icon headlamps w/o chargers from Amazon.com for $51.82 each. That's right in the price range I was thinking of. It definitely looks like a nice lamp. One thing that I like is the strap that goes over the head. That makes it like wearing a baseball cap.
Brad, I will take your advice and carry three sets of batteries in my pack, just in case.
Thanks again for all your recommendations!!!
