Excellent regulators, hard-to-find parts

I have a set of these regulators installed in my chest freezer conversion kegerator. It's nice to be able to set the pressure by hand turning the knob (I can never find a screwdriver when I want one), and there's also a hand-tightened ring to prevent accidental changes. They also look very impressive. Be sure you get the right number linked up out of the box though (between 1 and 4), since Micromatic does not stock the coupler you'll need to add more. Also, the high pressure side is right hand threaded, which seems to be less common than left hand threaded. When I contacted Micromatic they also said the shutoff valves do not have check balls, which shouldn't be an issue with commercial kegs since most commercial couplers come with a check ball, but I'm planning on investigating adding a check valve when I add some homebrew kegs. Overall, I've had these for a few weeks and I've been happy with them.
