It's different but I wouldn't say it's flimsy. The Jet J/P fence does seem sloppy when moving it but once tightened down it's solid. I modified my Jet fence so it would tilt 45 degrees both ways. Even with the longer supports it still seems solid. One thing with an aluminum extrusions vs. cast iron--aluminum doesn't warp. Remember the Delta cast iron jointer fence fiasco when they had to replace a bunch of 'em? Though I guess that's only an issue with new castings.
