I don't own this site nor am I affiliated with it: www.960.gs it's a pretty fantastic set of grid templates for web design. it also includes the template's CSS files and other goodies. it not only enhances the overall cleanliness of my web design but I can crank out a page 2x faster than before, especially when it comes to slicing and coding. you probably are all familiar with it already. but it's changed how i do web design..
