Bosch Multi-X

This Swiss-made tool weighs in at 3.7 pounds and has a hefty motor with a soft, sweet-sounding start-up. It runs between 8,000 and 20,000 oscillations per minute, but even at its lower speeds, it was by far the most effective we tested. Unlike the Rockwell, it can't accept competitors' accessories, so you'll have to start with the included five blades and 15 sanding sheets and work from there. [$200; boschtools.com]
