If you are in the US this is especially good since you would receive it in just a few days from Bryan. Great service. That was actually the first LED flashlight that I bought. As a bonus you could run it on 1 x CR123a if you want.
Sipik Sk-68 is also a good, cheap flashlight ($8 shipped or less). Love mine! Very bright on 14500 and will still run on 1 X AA if you need to. Good flood, good throw when zoomed.

Another option that is highly spoke of around here is the Romisen RC-29 which you can get for $15 shipped from DX. Like the SK-68 it will run on 1 X 14500 or 1 X AA, and is very bright on 14500. Flood or zoom. This is my next purchase.
