Ratcheting screwdrivers aren't all that new, but this is by far the best one I've found. It's better made and less expensive than a lot of others out there, and - at my house at least - replaces a whole bunch of other screwdrivers in my toolbox. Its advantages over the Snap-On and Sears models are innumerable, but principally, the knob on the shaft that allows the bit to turn four times for every handle turn - it's as fast as a drill driver in this respect, and is a huge time saver for long screws. It also has far better bit storage is easier and faster and much more secure than the clips on the Sears model. $17 from Bubba Deals, probably as good a price at your local independent hardware store.
