I stick to 5 gallons and have no plans to go larger (house size) what do I really need to be happy and have a "house batch" always in the keg? Do I need a small fridge? (The fiancé will not let me cut into her new LG) Looking for what I should invest and where to buy (NB or local store?).....any help is greatly appreciated! Just joined today and looking forward to growing my knowledge, thanks guys!
