First, I'm kinda curious what brands/models some of you guys are using. I tried the Home Cheapo $400 CST/Berger. It was a manual level laser which I found frustrating to constantly check and readjust for level. so, I think I want a self leveling unit, although I'm wondering how to set it to a pitch, say for your 2% on a walkway or patio. Do most self leveling lasers have the ability to use in manual mode?
