In winemaker magazine! Gas Getter.com inventor is guy Rhone. His website has lots of tutorials. I was skeptical at first- but drinking 6 month old Cab (from kit) and its wise beyond its months! I use the all in one pump for racking, but this beast is built superbly and love the ability to sit back and have the power tools do all the work. I bought the gas getter with 6 ports--- but he has many styles/models.
