Just been into the House Of Fraser Outlet store in Swindon and picked up one of these bad boys at an incredible price. They had about another 4 left. Unfortunately there are only 2 of these stores in the country, Swindon and Leics but if you know anyone near them, you could always ask them to pick one up for you.
Takes 4,5 and 6 litre kegs, and also has a container for putting wine and squashes in. If you purchase the optional co2 dispenser then you can also use it for fizzy drinks.
