Not sure precisely which part of your post your smiley is for. My guess is the $30 budget.
HID is awesome if you can afford it: unmatched overall output, best output/input power ratio, and good/very good shock resistance. They have fair/poor battery life because they're putting out 3-5 times the light needed, and they're expensive. Of course, building a comparable-output system with multiple high-flux LEDs will be nearly as expensive and
heavy due to the heatsinking required.
