I have one Eagletac 14500, it's fine.
I also have 4 Eneloops, they're fine.
The Eneloops were cheaper. The 14500 does have the neat 500lm trick but I'd save your pennies and buy the Eneloops. You can get more for the same amount of money which means if you're going away you can just grab a handful.
Nitecore charger is good.
