The other day i picked up my 1st set of Bessey K-Body Clamps.
I got 2 24in, 2 40in, and the KP blocks. Rockler advertised this as a set for about $160. However, they didn't have them as a box set, so one of the sales guys took all of the seperate items and rang them out as the package. It actually came out to about $2 less than the price in the catalog.
Here you can see I already have the 24in'ers hard at work on a cutting board I'm doing.
