I have been questing for an inexpensive 44DD if someone knows someone.
I started with Streamlight Microstream for my EDC pouch. It was a hair too wide in diameter to fit into my Leatherman pouch so went searching. I was fortunate enough to find someone on the EDCforum that recommended a China made flashlight from http://www.cnqualitygoods.com/. The specific light was a AAA with a very small diameter (smaller than the 14mm of the Microstream) at 11mm.
Behold the CGQ-S1. Comparing to the Microstream.
$15 USD, 80 lumen, SS construction. Ric is super nice and great shipping from China. I'm not usually a China guy, but it had everything I needed (size) and a reasonable price.
I also wear a Nano on my keychain and have a Spotlight Speck in route for a neck light.
I do kind of dig the new 47 Preon 0. I like the glow reflector. I also like the DQG-III. Both around $30 USD.
