Generally speaking, plasmas typically look better and handle video better than their corresponding LCD models. Add to that, you get more plasma for the same money, or spend less for the same size plasma as the LCD models.
Plasma vs. LCD is debated and compared all over the place (including this site) and is worth reading about. But, everytime I read about LCD the bottom line ends up being that plasma looks better and costs less.
If you aren't a video game or PC nut who must have a static image up on screen for hours on end, then plasma is a great way to go. But, if burn-in is a very real possibility in your scenario, then think long and hard before switching from LCD to plasma.
