If you plan to put up drywall… BUY THESE TWO TOOLS. You will thank me. I have always put up sheetrock with a cordless screwdriver. It seemed to work pretty well but since I had a ton of sheetrock to put up, I bought the DeWalt cordless drywall screwdriver and collated screw accessory. It took only one sheet of drywall to come to the realization...
