Kits don't seem badly priced, ok you could probably get them cheaper from tesco or wilko but they seem to have a lot of higher quality kits. And they are local and very knowledgable. I've got a keg I blagged off freecycle, seals etc were a little old and tired, got replacement parts for not much money.
I'm nothing to do with them by the way, was just personally very impressed all round.
