Without wishing to derail - SON are great, be a bit wary of the delux - it's lighter but cannot power a light and charge at the some time like a SON28 can. PV-8 are a lot cheaper and have a fundamentally different internal design (different magnet arrangement) and are generally as light.
The B and M Lumotec U lights are amazing (can charge and put out a goodly amount of light)
