My experiences with Black & Decker have been far more positive...lucky me?  I had a 12V Firestorm cordless drill outperform 3 Craftsman 18V drills...the only thing I ever needed for it was a second battery pack so that I could make quick-changes when I'd run out of juice.

The Craftsman drills, on the other hand, all developed VERY odd problems in the motor and died within two years each during the SAME PERIOD of TIME I owned the Firestorm.  The Craftsman drills were all purchased by my employer, who sworre by Craftsman, but as they were breaking with regularity, I'd bring in my B&D and use it...
