I bought this item a few years ago for my Bar at home. I love it and so do all the guys who come round. The only problem is getting the kegs. In the UK they charge around £32 - £45 per keg. There is only 6 litres in each keg (approx 11 pints) so its a bit expensive getting it from the UK.
Buying it from PerfectDraft (Netherlands) itself is cheaper ranging from £25 to £39 but you have to buy 4 at a time and the shipping is around £32.00, so still works out about £3 plus per pint. They also have deals on certain items so it works out a little cheaper if you buy 4 x Stella Artois for example. In the UK you can pay for each keg separately. Another problem is returning the kegs. When you buy them, there is an additional deposit charge which they will refund you back. The problem is they are heavy and you have to pay the postage shipping them back to the Netherlands. You cant return them to the UK Seller unless you bought the kegs from them. I myself have sent them to the tip as I cant be bothered messing about returning them. On the whole the item is amazing as you get chilled beer every time but the downs are the price of the kegs and then returning them. If your rich then its a truly an amazing item, if your not then it an expensive domestic pleasure.
