I hope this isn't in any FAQ page or anything, but can anyone tell me the difference between an 'S' and a 'U' suffix on a Sony TV model number? I have my eye on a Sony KV32HX15. I have seen it in Currys with a 'U', but also online at Empiredirect with an 'S'. Also, has anyone got either version, are they any good? Thanks for any help you can give.
