DeWalt, Makita and Milwalkee are all good, but the cost is not so good.. Stay away from the Harbor freight ( I stripped out the gears of a B/N corded drill in seconds, there cordless versions can't be any better )... I have a couple B&D cordless drills, and they are adaquate for what I use them for, and if the batteries go bad, they won't break the bank.
