I've been brewing and bottling for about 4 years and want to move to kegging. I'm looking to convert a fridge into a kegerator and eventually have a two tap (or faucet for my US brothers!) tower. I've seen regulators with two gas outputs to run of one gas cylinder - but these are proving difficult to source. Does this mean I would need two gas cylinders with two regulators if I can't source this item? (I' d have thought this would be a common problem for those using more than one keg at a time) Also, I've got a soda stream gas cylinder. Would this be sufficient to run two kegs from? Or would I be better going for one SS cylinder for each? Or are SS cylinders simply not recommended? Thanks for your help!!
