Ryobi AirStrike Brad Nailer

Nail guns are fast and powerful, but they require you to drag around compressor hoses or gas-filled canisters, no matter how small the job. The AirStrike ditches all of that but still spits out air with enough energy to drive in 18-gauge nails up to two inches long – about 700 of them per charge. [$130; ryobitools.com]
