I just got a CygoLite Turbo 740. It is very bright and I like the beam pattern (very bright center spot with a dimmer and much wider cone around the center spot). For the price it is hard to find anything much brighter. It is a 2 piece light however, so there is the extra hassle of finding a place to strap the battery. Also, if you lock your bike in a higher crime area, there are 2 pieces to remove rather than 1.
