Apart from Avtex company which attracts consistent high reviews but very expensive to buy has anyone come across a cheaper tv that works well in a caravan. Not tinny sound etc as some reviewers have found on their purchase. It would be nice to have one whilst away to watch the olympics. Not worried about getting sky etc, just one that is easy to set up and does what its supposed to do!! Thanks in anticipation if anyone can come up with a good suggestion from experience.Thankyou
