Anthem, I'm digging that NiteRider. You lose a little light power but it's pretty damn light. I figure I could use that for road riding and when I hit the trails, pick up the MiNewt usb-plus and helmet mount it.
FSR, that stella you linked was the one I was originally considering. I hear ya in regards to spending money on a light setup. I'll probably trail ride 1-2x's a yr but road ride more often when it starts getting darker earlier.
