Sharp, Sony or Samsung. Excuse my brief answer but that was for your brief question! If you give more detail into usage preferences, then I am sure many people can help here. :-D
Yes I saw that you mentioned SD (Standard Definition) but is that all you will use it for? No game consoles connected? Also, what connections do your devices have? HDMI, component? etc... The three brands I mentioned are the leaders in LCD TV's, so you can shop around and decide for yourself which suits your preference better.
No games, no hdmi at present. I am waitng for Freesat HD, but goodness knows when and if the box will be any good in Spain, thats why i am particularly interested in a good performance on an LCD set.
