The keg set up

Not sure if it is relevent to the forum but a couple of people asked me earlier about the keg in the fridge system i am hoping to get running soon. The way i plan to do it just ferment like normal in the fermenter , then syphon into either 18 or 20 litre keg. Any excess can be bottled like normal home brew. Then all you need is to hire some gas, fit the tap through the door of the fridge and drill another hole in the side of the fridge to run the gas line through. The keg needs to be level(a mate of mine uses an old bessa brick to sit the keg on) The whole set-up costs $300 plus gas. You only need one keg as you can brew ahead and store in plastic containers in the fridge. Only takes 5 mins to refill keg and away you go again. Any other ways of doing it??????????
