I love my 50" Panasonic Plasma, ~$1400. I've been using it more for HDTV and PS3. But with the new addition of the Wii to my family, I'm sure it will get even more use.
Watch websites like hot-deals.org (I have no affiliation, they just post good deals) for good prices on electronics.
As far as burn-in goes... TV manufacturers still provide warnings in their literature about burn in, but after 7 months of TV and video games I don't see a problem. The most important thing is not to set the TV to 'Vivid' color or brightness and leave your DVD player / video game / whatever paused forever.
