The problem you will have is Calmini won't ship to the UK they will insist that you buy through Specialist Leisure who are the official importer. If you do find someone that will ship it will be very costly, its a heavy kit. On top of that you will have to pay import duty and VAT. Most carriers will also charge you around a tenner for dealing with the excise paperwork. SL are no worse than most importers I've dealt with, the going rate is usually £1 per $1
