With Black Friday a week away, I too am looking for a good deal on a good LED rechargeable work light. I have a Black & Decker- Bright Bar and it is finally on it's last legs. It has been a good light for me as I ended up buying two (one at work and one for home). The weak point is the batteries and charger. If you overcharge it, it will kill the battery.
To me, an ideal light would be very similar to the Bright Bar, but would use a battery from a drill or similar rechargeable tool.
