With most household paint jobs the majority of the work is the prep. Rafters with brushes and rollers would cut down some prep, but the time spent actually painting would take days compared to hours with a sprayer.
Make sure your spray tip is installed correctly and close your mouth before pulling the trigger!!! It was like a paint bomb going off in the movies, every surface in the small laundry room was covered and I was standing there dazed with a face full of paint for a long few seconds before I realized what happened.
