Here in Ohio they've had both the Megabrite LED Keychain lights on sale for less than $2 and Energizer AA Hard Case flashlights on sale for about $5 each, not a bad deal.

I took out the the CR2014 button cells from the cheapo keychain lights to use for my Photons and Inovas(2 in each one, and I bought four of them) and spent about $25 dollars at two Target stores, clearing out the AA Hard Case flashlights. I bought six of them and you should have seen the looks on the cashier's face! Her exact words were something along the lines of, "I think you've watched Darkness Falls one too many times!"

The AA flashlights I put in a drawer and numbered them with a Sharpie from 1-6. When the power goes out I plan to pass them around to my family and my neighbors next door in our apartment building.
