Since Lowe's is blowing out their inventories of 24", 40" & 50" Bessey K-body clamps, I've been picking up a few on sale. I think I've got an even dozen now.

So far, these are the only sizes of K-bodies that I have in my shop as I'm still relatively new to woodworking. Are there other sizes I should be considering (especially given the current price reductions)?
