A friend of mine picked up a Cobalt screwdriver at Lowe's for like $50. Had so much torque it stripped 3 screws when I borrowed it. I have a ~$10 Black and Decker that works pretty well but is slow.
Of course I have the big bulky drill/drivers, but I'm looking for a smaller one for those jobs that have dozens of locks.
So, what is your favorite small cordless screwdriver?
