I have 2 of these mini Ultrafires that use 1 AA battery or 14500, one with zoom and one with 3 modes. I paid about $3.50 each shipped from China. They are very bright for a small flashlight.
Sorry, I know it's an old thread. I'm not a hardcore flashlight collector, but once in a while the urge comes on to buy one. A few months back I bought something similar to these mini Ultrafires, but Housbell branded. They have zoom and 3 light modes. They are 2 for $8 from Amazon, shipped from US, so you don't have to wait for them to arrive from China. Good little lights.
I also just ordered this Anker LC90 one. It uses a Cree LED XM-L2 chip and comes with an 18650 battery and can be re-charged directly in the body, using the provided mini-USB cable. Although, if you're big into flashlights, you probably already own a standalone 18650 battery charger, so that may not be of much interest.
