For Christmas, my brother Ed bought me this "Cross Line & Laser Plumb". I finally made use of it this evening with the start of the panel wainscoting (pictures tomorrow).
So, here it is in action (be careful not to stare at the laser too long):
Remodeling a quaint little farmhouse in Oregon, and getting loads of splinters along the way.

I ended up buying it at Lowes last week for $233. The Home Depot that I originally found it had no more on the floor, and they were clueless as to when they'd be getting more in. Actually, they were clueless as to the very product I was talking about.
Imagine that....Home Depot not knowing anything about the products they sell.
