Cordless drill/driver/impact for dummies!

I use a 20MAX Dewalt 1/4 impact. At 117 ft/lbs its a little light but plenty strong for any nut breaking up to 5/8 on the motor or under the car. ITs pretty short too so not hard to handle. We had to start using these impacts as the drills we had were torquing wrists and causing injuries! Has a nice LED light on it too. Charges very fast too. make sure you get a battery with it as they sell them bare too for the guys who already have the batteries.
