[Larry in Bend]

I carry an Arc 1xAAA and wouldn't be without it. Arc is out of business but there are many for sale on Ebay. In the small but larger category, I recently purchased a Pelican M6, 2x123 lithium incandesent. At 74 Lumens it's very bright and, in my opinion, you get more for your money (about $40) than with Surefire (I like my Surefires, too, but it's hard to find an E2E for less than $90 and a new bulb runs close to $20. I am aware of the rubber/plastic Surefires but have no experience with them). Anyway, I got my pelican from Batterystation.com and I can recommend them.
