Cheap laser levels

http://www.woot.com/
2 laser levels for 11$ shipped.

Its on for sale today only 10/21/08. tomorrow will be a different item. Because it says "Dual laser beam, horizontal or vertical" you can probably get 2 good diffraction gratings out of each. or you can just use one to level stuff! lol..

the site is good. they only sell one item a day, but they have pretty good deals on most items.

Cool, that's cheap. the story on that site is a funny/odd read.
