I think they are all pretty much the same. Some have some extra features like the Kreg with the wider mount and space for something else. I personally got the silver aluminum heavy duty 8' sections from Peachtree years ago at the local woodworking show. It has held up well, and came with 4 knobs and bolts. In fact, I need one more section for the assembly table I'm building. Jim.
