$50 · Coopers Micro Brewery kit.

Works really well. All you need is mix, available everywhere, and some bottles. Comes with everything from the original kit except mix and bottles. Has about 4 packs of new bottle caps. Uses brown or green plastic bottles. Readily available. This is probably the easiest way to make home brew that I have seen. Comes with extra bucket for transfer as I found that the best way to finish up. I haven't got the space for it any more. Makes a full 21 Ltrs from a can of beer mix.
