I have 2 newer ones, they're crap compared to the old ones, but still not bad, I think it was a 2 for 1 sale on Amazon. I use one as a base for my sliding compound miter saw, it's *just slightly* too weak, but it works.
I also have a vintage one that would mount on TOP of an existing workbench, it has synthetic clamps with steel edges, and can tilt.
