Hi Anna,
Firstly brand you have selected are the best...still Samsung is better....Secondly, my suggestion is don't go for Plasma TVs as they consume more electricity & soon fading out of market. Why not try latest LCD TVs....Plasma TVs employ a matrix of tiny plasma gas cells that are charged by precise electrical voltage to create a picture. In the case of LCD panels, liquid crystal display make up the screen. Imagine liquid crystal pressed between two glass plates to which varying electrical charge is applied to create an image. Plasma don't last long (30,000 to 60,000 hrs - watching hours) compared to LCD (60,000 hrs)
Though both have their pros & cons...just a tiny sneak peek for you....
Some Pros....
* LCD TVs offer more pixels and so you can see more minute details
* LCD TVs are said to consume up to 30% less power than plasmas
* Plasma screens render black better than LCD TVs. The contrast and level of detail are therefore better
* Plasmas offer better viewing angles. It allows you to get a clear picture even from acute angles
I guess first two are more important & relevant, right....choice is yours.

Hope you find this info beneficial and Happy Shopping !!!!!
