Reply to Where to buy the s4 from?

Even after reading about the numerous problems I still have my heart set on an s4 (hope this is a wise decision!). My question now is where to buy it from? I live in the UK so is the saving that I will make by ordering from the US big enough to make it worth it? With all the problems I believe buying from a UK store is wise because of the warranty. Dv247 are selling them with a 4 year warranty which is tempting. Any other good deals knocking around? What is the final price from DJTT delivered to the Uk including taxes etc?
