Does that $22 light also have recharging pains?
It requires a little bit of discipline but it's not that onerous. My round trip commute is long enough that I need to charge after every commute but all I have to do is unplug the battery and plug it into a charger. I have forgotten to charge a pack on occasion but I have several packs that I cycle through so I always have a fresh pack for each lamp (I use 3) whenever I want to ride. It's just not that big of a deal.
