I have the Jetlites x-52 and fu-2.
http://jetlites.com/ Both about 900 lumens. I've had them a couple of years and have been flawless. Durable, good battery life. I have friends who buy the chinese lights every year for cheap, but they are cheaply made and don't really last all that long.
MTBR does a yearly bike light review that's pretty good.

A friend has asked to borrow my lights this year. She's doing it solo. If they don't need them, you can use mine. PM me in a couple of days to remind me if you haven't found anything.
