Here’s the kind I went with after some research into it: The Micro Matic Touch: The Best Quality Beverage Dispensing Systems
Micromatic is known for quality. They have two models basic and premium. I went with the premium mainly because I don’t need a screwdriver to change pressure settings. These units are very consistent. I have two of them, a single like the link, and a double, so I can feed two different pressures to two kegs in one kegerator off of one tank.
