Hi I'm looking to buy a 28" widescreen TV. Can anyone advise on the difference between the Panasonic TX28PS1 and TX28PS1C? I have up to £500 to spend and would be grateful for any advice on best makes models etc. Listening to the guys in Currys & Comet, they all seem to have different opinons and I'm not sure how much faith I have in them anyway! Thanks!
