I think I did see some in UK on the web. There are lists of qxci practitioners. I do not know where I saw it, but you should do a search and email companies that sell the machines.
Just seen your posting asking for practioners of QXCI- there are many of us! I now use the new updated version of the QXCI called the SCIO . If you wish to see my website see www.scio-wellness.com
