Got my co2 regulator.  Went with a Kegco dual regulator.  this way I can carb up a new keg an leave the others at serving pressure.



Also got a counter-pressure bottle filler.  Never used one of these, but it is supposed to allow you to fill bottles from the tap without causing it to foam up or become oxiginated.  this one got really good reviews and it fits on the tap faucets and has a ball-lock connection for the purge valve.
