I have two 12-inch blades. One blue Irwin 100-tooth that's been used but still in excellent shape. One 60-tooth Irwin combination blade that's barely been used and in even better shape. Both 12-inch blades for only $20.
If you look at the last picture, I also have four Craftsman small part organizers. All four for $15...or only $10 with the above blades.
