Having recently rediscovered Sigmasport for computers and lights, I'll put in my vote for the Buster 600 (BUSTER 600). At $99 it's more than the magic shines of the world, but less than L&M, NiteRider, etc. My bias is for a self contained light, meaning no cords to separate batteries, and this fits that bill. The Buster is aluminum, so nice and rugged. It's well sealed from water. It has a good beam pattern, good runtime (2 hours at 600 lumen, 5 hours at 250, 11 hours at 110), good attachment to the bike. It also has 70% and 30% battery level indicators, so I know well in advance if I need to switch to a lower output to conserve energy. Just a great light.
