My 55" Phillips RPTV was covered by my extended warranty. It is unrepairable. :) So now I need advice on a new RPTV. I would like one that is similar size. With good features. Please advice.

Check out this thread about the Sony A3000, which comes in 50", 55", and 60" models.

The Mit 57734 and 57833 are great sets, the Sony A-3000 also seems to be a great set,
the Sony A-3000 and Mit 833 has about the same features, (Mit also has 3D gaming), The difference being the Sony comes in 50",55" and 60", The Mit in 57",65" and 73".
