Driving drywall screws by hand is way to tiresome if you have an entire house to do. You can use a drill, but most drywall installation experts recommend using a screw gun, also referred to as a drywall screwdriver. I've seen people try using a regular drill with variable speeds to put in drywall screws and more often than not they end up tearing the drywall paper and ruining it. The benefit of using a screw gun is that the tool has a clutch and special collar so that when your screw reaches a certain depth, the driving motion from the gun will stop. Almost all craftsman who install drywall for a living own a screw gun for this reason. Beyond drywall, screwdrivers and screwguns are used for framing and decking with wood or steel. The top brands are Milwaukee, Senco, Makita, DeWalt, Bosch, Hitachi, and Porter Cable. Expect to spend at least $60 for the basic models and upwards of $200 for the collated screwdrivers with autofeed systems.
