we have a 42" Panasonic plasma with built in freesat. Brill picture if a tad thirsty on the electric.
One thing we considered when we bought a few months ago was the potential cost of repairs out of warranty. We bought from John Lewis which includes a 5yr warranty. We also bought a 37" LG LCD for our teenage kid's games room from Richer Sounds whose 5yr warranty is just an extra 10%. When you compare what some high street outlets charge for extended warranty these two were both good value.
Look at the bottom line - price+extended warranty+delivery when comparing prices.
Good hunting and let us know the eventual winner.
