Just found this on Amazon for £18.77 with free delivery, sold by Mymemory. RRP £60 which i know is over priced and never at RRP price but thought £18.77 was a good price if anyone is looking for one, Its the Gen 3 so the latest version to date. Never tried one but seems a good idea. Also i know its been cheaper in the past but seems a good price still.
Its £26.96 on Mymemory website.
