my 2 strong recommendations in the 1xAAA section:
overpriced yet unsurpassed: fenix lDo1 r4 (32.00$ on ebay)
was underpriced during market introduction: tank e09 (xp-e r3)
if i had 30$ at hand and had to pick 1 particular model, i would grab 3 copies of the e09. so there you have it. (and if i had 90$ at hand and ..etc.., then i would grab 3 copies of the lDo1. hope you understand haha)
