If You are near a Woodcraft store they carry the Jet and Bessey lines of clamps. They also have Jorgenson and some Woodriver ones too. The Jet and Bessey seem to be the best quality, very stout with the Jets having more features but similar build quality to the Bessey clamps. Of course the Jet clamps cost more due to having scales printed on the bars as well as a separate lever to release the clamp head for positioning. I have some Bessey's, Jogenson and Woodriver clamps. I like the Bessey and Jorgenson ones the best and hope to get some Jet clamps in the future. And yes you can never have enough clamps. Same goes for routers, but that is another complete topic for later contemplation.
