An update for you...
I called up Powerlet today (a Saturday) and talked with the owner / founder John. In short, I rode out and met with him, he showed me their products. and set me up with exactly what I need. I've already heard from others about the quality of Powerlet products, and now that I know it's backed by a nice, customer-oriented group of people, I highly recommend Powerlet as well.
And keep your eyes open for an announcement... they've started construction on a new retail space that stands to become "a destination spot" for riders. Anticipated grand opening is in a couple months.
