I am late to the headlamp party. In years past I had a couple of bulky Streamlight lamps and didn't find them useful. But that changed when I got a small Petzl Tikkina! Now I have maybe 8-10 Petzl headlamps about 8-10 Black Diamond lamps. IMO they're both great and have superb options from $15-$100.
