Just asked a contractor friend, get a lithium battery powered DeWalt impact driver 20 volt-max impact driver. Bought the combo kit for $229 at Home Depot.
Batteries are as much as a drill, when you get the combo pack you are basically getting a free drill.
(case, 2 different drills, 2 lithium batteries, charger)
