Anyone seen one of these?

(Other sites have pics; this was just the lowest price I saw with a quick search.)

I just saw it in a car magazine about an LS motor installation. Apparently, the pressure is set at ~58 lbs, but that's the approximate set point for RX-8 cars, right? I've already set up my dual fuel pumps, dual GM filters as used by Ed A, and an aftermarket 'hot rod' adjustable regulator, but this device looks attractive. The weight savings (& money savings) seem to make it an attractive option.The only downside that's immediately comes to mind is whether the entire assembly must be replaced to change the filter.
