I have done a few kits since Christmas and the whole thing has escalted quite quickly.I just did my first all grain brew yesterday.
I got my kit off ebay, full set up, boiler, mash tub,chiller, FV, barrel and bottles, with some malt as well for £70. Very happy, in excellent condition only used a couple of times.
However, if you have any half decent DIY skills you can make up a lot of the stuff yourself. The mash tub is just a 30l coolbox fitted with a plastic tap and a strainer, they sell them for about £75, way overpriced.
The best thing I have done is make a brewfridge from an old fridge, heater and temperature controller.
I did find all grain very hard work and quite messy, hopefully it will get better as I get used to it.
