I've been running a Sanyo H27/Panasonic dynamo hub purchased at soma fab shop for the princely sum of 22.00, combined with a B&M IQ-XS for the last 8 months or so (sporadically - I'm not a hard core every day no matter what commuter) and its been fantastic. Built the wheel myself, got a good price on the lights, and haven't looked back. I very much like not having to fiddle with batteries, and knowing my light will last as long as I will (I won't outride the battery life). I do use a battery powered blinky light on the rear. In fact, I like it so much that I'll be building another dynamo wheel using the same hub for my 2nd commuter bike over the Christmas break. This will power a SuperNova E3 Pure 3, so I'm interested to compare the two lights.....
