I just went through this process myself. I ended up buying a Thrunite Archer 1a, a Nitecore i4 intellicharger, and some Aa rechargeable nihm batteries from "the big river". For a little more money, a Nitecore p12 might work also. :)
Since I ordered it on December 28th but didn't receive it until January 2nd, I think it qualifies as the last purchase of 2013 and the first of 2014. A Fenix E05. Fantastic keychain light!
Just ordered a Fenix E05 for my keychain to replace the Streamlight microstream I handed down to my daughter. The microstream has met my needs very well, but I took the opportunity to go just a little bit smaller for my edc.
