I've been playing with various laser levels in order to try and level out my walls. I've reviewed any number of sites and the craftsman $89 model is highly touted. Baloney. I bought one today and you can't see the line at more than a few feet except in the dark. Piece of crap. The first unit I bought was from Lowes, a $32 Kobalt compact level with a laser. Best I've tried so far. I suppose if you have the $$ you can buy into a 3 figure unit, but I don't.
