Hi Ian, The main reason of the price different between the Canon 550D and the Kiss X4 is due to the supply cost is lower for Kiss X4, so that we are able to set it at a lower price. The two cameras have the same functionality and features, except that it has a different name tags on the body and the kiss X4 only has two language settings, English and Japanese. Both cameras are offered with DigitalRev's 12 month local warranty, which you can repair the camera locally in the UK for manufacture defects. You can learn more about the warranty at http://www.digitalrev.com/help/digitalrev-12-month-warranty-with/MzQ_A The prices you see on website are all inclusive, as well as Free shipping is offered. Please feel free to let me know if you have any further questions.
