Scott Riese put me on to this nifty laser. It has an attachment cap that
you put over the beam dot and it converts to a line. So what you may say,
well it has a built in level and a tripod so if you want to make sure your le or te
are dead straight, ya gotta own one of these. Sure beats the dickens out of a straight edge and talk about getting the tail feathers dead on? Comes with batteries so you can check it out without scrounging for batteries. Best part, it's $9.99 at harbor freight.
you may want to see it on their web site so here's the item number: 41102.
