2 suggestions: I did review a Lightwave Illuminator, and it seemed to be a good, durable light, but a little topheavy.
For a really cheap option:
If you have the time an patience to do a mod, I (and many others) replaced the incandescent bulb in the Rayovac "Adventurelite" kids headlamp from WalMart with a Luxeon Star (buy from Peter's website). This works very well and the total cost for parts was about $22. The headlamp is OK by itself (about the same output as a minimag) if you want to stick with it as-is. Not bad for six bucks.
