I would like to buy a MX-850i / MRF300i for use in the UK, but I understand that the 418MHz frequency is being released for use by TETRA (high power / long range mobile phone use), which will cause serious interference issues for lower power domestic applications such as remote controls. But I have also read that URC produces some of its kit in a 433MHz version (with an "i" suffix).

Does anyone know where I can purchase an MX 850i and RMF300i - preferably at a reasonably discounted price - and preferably from a approved dealer to allow me to register the remote with URC for software download? (I would be equally happy to buy from a UK dealer or from a US dealer willing to ship to the UK.)
