Price: $76, skiltools.com 

We doubt you'll need the hulking power of a full-sized electric drill. So to handle the majority of your household tasks, we suggest getting a compact, palm-sized piece like the Skil iX03. With a speed of 200 RPM it's capable of helping you install your curtains or blinds, hang pictures on your wall, and assemble various good. And you'll rarely have to worry about picking up the iX03 to find it juice-less: the lithium-ion battery is good for 18 months on a single charge.
