The Craftsman 3-speed impact driver kit is $62 for store pickup or $72 shipped. This is about the lowest price you'll find, save for perhaps a BF doorbuster.
The Craftsman Bolt-On 20v drill/driver is $48 for store pickup or $57 shipped. Maybe not as great a deal as the impact but offers some more versatility for weekend warriors.
