Yeah. TSC has them at that price too. I have a plastic bodied one from years ago that seem to have better LEDs and I think works better by the in store test. I can pick my way home with it. So I picked one of these up knowing thanks to Pe2er that it can be a host down the road and maybe if the plastic one IS better, do a parts swap, and let Kathryn have the lesser for her purse. How much throw do you need to see to the bottom of a purse, anyway? The three name brand triple A's are $1.95 bought in an eight pack, so there is likely $1.50 worth of batteries in it.
Must admit that I have been bitten by the bug also. Have more bike and flashlights than a person needs. My son does not mind
Our local "Blokker" and "Action" also sell these lights for around €2. The LEDs in them are not so bright as the light from Dx, but that would not be an issue when you plan to convert it. The head however doe snot unscrew from these cheaper lights, so that would change the design some.
