Black Diamond Spot is pretty sweet for the price as long as you don't mind an external battery pack. Takes AA batteries instead of AAAs, so it's heavier but it lasts quite a long time.
Maybe you actually have a BD Icon ?

I have a BD Spot -- it takes AAA's and has no external battery pack. I've used it for alpine starts & mountaineering with no issues. Got it when Sierra Trading Post was clearing them out last year.
Most of the 1 watt LED headlamps are pretty decent for that kind of thing. Much like with PC's the technology keeps evolving, so almost anything you buy is going to be "obsolete" within the next year or two. More efficient LED's keep coming out as time goes on.
My criteria for a mountaineering headlamp is: (a) costs $30 or less, (b) weighs less than 4 oz w/batteries. I also have a couple of Princeton Tec EOS -- a newer 50 lumen one and the older 25 ? lumen one -- I understand there is now a 70 lumen model.
If I was into caving or serious nighttime mountain-biking I'd probably want something expensive and really bright, but I just don't see the point otherwise.
