For a laser go to ffx website the lecia laser on there for £100 is ideal, I've got 4 lasers now and I use the lecia most, oys a self leveling city cross line and if you put it on the tripod it comes with will ping a line in one direction about 15m, it doesn't come with a magnet back plate like the dewalt bit I use a cheap steel rule screwed to the wall and can adjust the magnet on tripod to suit, neat ?100 laser on my opinion
