Hi, Hope to be a regular on these boards. It's taken me a while to find a good one! I have finally decided after a bit of research, to go against a 100hz TV and have pretty much come to the conclusion that I will get the Sony KD28DX50 (still open to suggestions otherwise), but just wanted to clarify what (if any) the differences were between the above 3 models. Is the KD28DX51 exactly the same as the KD28DX50 specs wise except a different design? I think I actually prefer the older, all-silver design of the KD28DX50. And furthermore, is there any difference between the KD28DX50U and KD28DX50? Why the 'U'? To sum things up in general I'm just looking to get a TV less than £500 which has IDTV, NTSC/PAL compatible, S-video, and is good quality and reliable. Can I throw one more thing in? What improvements were made to the Sony KD28DL11/DL10 for it to become the KD28DX50?
