Scott,
I have a Porter Cable and a CST/berger self leveling lazer level we use all the time. What you want is a rotary lazer level that will snap a line on the wall. It is a dot that rotates on an axis. you can control the speed. They are both professional grade tools and are very accurate. I think they may make a cheaper or a home owner's grade level. They run about 800-1000 bucks. What are you doing with them? For your 911s???
Jeff
