I have been putting this off as well, my fridge recently broke so I have been spending time on a new keezer. Now that it is done I plan to get started on this with in the next little while. Did you guys get the parts for this online or from a store? I have a used regulator, anyone have any idea if there would be issue with using that? I would run some CO2 through it to get the propane out, seems like it would be fine but I don't know much about gases really.
