Here's a left field suggestion - Xiaomi Redmi Note 2 32gb for less than £120 from Gearbest's EU warehouse so guaranteed no customs charges. Specs-wise it absolutely wipes the floor with any £150 UK sourced Android handset! Yes, the warranty will be an issue but Xiaomi are one of the biggest mobile manufacturers in the world and make very reliable products.
