There isn't much to these clamps and thats what makes them so darn useful. It seems like the race is on to see who can build a better clamp. Perhaps pipe clamps are like the mouse trap so called improvements have been made. But are they really better? granted there are some nice clamps out there but don't overlook the simplicity of the jorgenson. It's tried true and timeless not to mention very inexpensive. I choose to use galvenized pipe instead of black it tends to be cheaper and won't rust up and stain your project. Now get out there and clamp something.
