As I said in another topic, although I own the PILA, I think the WP2 II might be a nice sweet spot for many people.
It also has the USB output, so you can charge your cell phone on it.
I will just repeat WHY nobody should buy a cheap charger:
The other thing people don't think about is that a good charger will take care of the health and longevity of your batteries.
Heck, I only use AW batts and they are not cheap. The cheap chargers have terrible charging algorithms, and cheap chargers are often constant current, which is not good.
A good charger is also safer in that it won't overcharge your batteries (which would also decrease their lifespan.)
Cheap chargers are for back up or emergencies or if small, maybe a travel charger . I rely on my PV and without good batts and charger, you're reduciing the whole picture
I lurk on all those "flashlight" forums, and keep up with the tests the guys there do.
2-bay chargers are also probably faster and more efficient than 6 bay chargers.
