At the recommendation of someone here I bought a Fenix:
DealExtreme: $17.30 Romisen RC-M4 3V~8V Cree 1-Mode Flashlight (2xCR123/1x18650)
It's just the size I'm looking for, plus it uses the 123 battery and the price is great. Now before I order a few more, I'm wondering if there's any other flashlight that's any brighter than this one.
Of course if it has a strobe mode, that'd be cool too.
