Hi Kim,
the Sony Bravia is a great TV... the last series, although had a slower refresh rate of just 8ms, it produced excellent colours... Due to the slower refresh rate, wasn't as good as some of the newer panels when it came to sports (although were great for movies)... The newer Bravias are meant to be quicker, but you do pay a premium for the name, but are of excellent quality... Seeing they are LCD TVs, the typical Plasma versus LCD debate comes to mind, but I must say they are nice TVs (the new ones being even better)...
There were rumours that the Sony TVs were built in the same factory as the Samsung LCDs TVs & shared the same panel (not all the internal componentry, as the internal componentry can make a differnce in picture smoothness - depending on what processors they run)...
For a small TV the size you are after, you can pay a premium for the Sony, but due to the size you would get a very good picture with something like a Samsung for much less $$$. I must say that the Sony may be built a little better & may last a little longer.
Cheers,
Manny.
