Right,
If you search through the threads on these forums you will find that even the best makes of TV have thier problems . It is a mine field out there!!. My best recomendation is to go out and get some good demos of sets and see what you think. The main brands I would look at are panasonic, sony and maybe Loewe (although they have slipped a bit in my book due to some problems I had with a 2 loewe Nemos tvs).
There is no subsitute for a good demo in my opinion, just remember that if you go to currys or comet that thier tvs are not normaly set up for the best viewing experince, so ask to see them running with a dvd . Also make sure that what ever DVD you do see on a demo It is not animation. Animated discs tend to look good on pretty much anything.
