Home Depot offer the Milwaukee M18 18-Volt Lithium-Ion Brushless 1/4" Hex Impact Driver Combo Kit with Backpack and Bit Set for $149.99 with free shipping. That's $150 off and the lowest price we could find, although it was a buck less in January. The driver generates up to 1,500" lbs. of torque and 2,800 RPM, while the bit set includes 18-pieces. A battery and charger are included.
