I think I will have a look at some shops at the weekend to find out what suits our needs best.
Not sure a look around the shops will help except of course with appearance & design. You'd be seeing all the models in a very artificial environment with shop lighting etc, making it very difficult to decide which you like. They'd all probably be showing some fantastic HD DVD which looks great on most if not all TVs which is OK if that's all you watch. Also, the way each has been set up with their individual menu picture settings, might mean that the one with the 'best' potential picture quality has been poorly setup making any viewing decision hopeless and irrelevant.
Finally what if the shops you choose don't have the latest models in stock or a good selection of others? The one that is just right for your needs may not even be there!
Advice. Do your research on what you want. Screen size, number of inputs, sound, appearance, web connectivity (if that's what you want) and Manufacturers along with other requirements YOU want from a set.
Draw up a short list, find the shops that have these and view JUST THEM. Don't be diverted to other ones which just happen to look good in the shop. That's how many buyers of cars have gone in to a showroom wanting a 4 seater saloon with auto transmission and come out having bought a flashy 2- seater manual sports coupe !
