Incra makes one that is not quite as aggressive but is along the same lines. Not quite as much of a horseshoe shape. If I needed more holding power I would go to an f-style clamp. There are similar jigs with slots for f-clamps to move about in instead of the field of t-nuts. If you come up dry here I wouldn't hesitate to email FWW and reference the article and ask for a source.
