After running about a year with a single co2 regulator feeding 6x 10 gallon. using the setup shown below. I'd like to see if there exist a better alternative out there with better/more professional needle valves to replace my cheaply made 6x co2 splitter. any pros please help point me to the right place or let me know if you sell 1 prebuilt. I am looking to keep the regulator and replace the 6x co2 splitter and possible also the single needle valve.
