You can pick up this Freeplay Sherpa LED at Target for just under $30. It has 7 LED's and 2 power settings, the high power seems plenty bright to me, but YRMV. I like that you can plug in the provided DC adapter and charge it's built in batteries or just crank the handle and power it via internal generator. On a full charge, I left it on set to low power and it was still providing usable light over 24 hours later! It's a little on the big/bulky side but it's great to be able to throw it in your BOB and not have to worry about changing batteries.

The other gadget in the picture is a Sony emergency radio/lLED. Also available at Target for about $40 but the LED is not all that bright.
