Cornelius Keg
Good value and work's well. You will need gas and connection equipment, but can be used with a sodastream gas bottle, the connection for this is quite expensive. The only down side to the keg is it's about 5ltr to small for a normal brew of 23ltr, and the rubber top and bottom tend to leave marks on your hands when handling it, but i would still recommend.
