I went with eFest Li-Mn versions, since they are reputed to be much safer than UltraFires under impact. Although I can't find them at 2 amps output. 😞

Flat, I got mine at VaporJedi.com for roughly $9 each including taxes and shipping. They only do credit card and Priority Post, but even then I reasoned it was a relatively good deal. EDIT: oops, not including charger. For that, I followed UKNerfWar's suggestion and got a Nitecore D4.
