You haven't mentioned anything that would help besides price. Several threads on this forum with lots of misinformation and some good information regarding making this decision.
How far will you be sitting from the screen?
Will you have HD programming or a Blu-Ray?
Will you be using it mainly as a computer monitor?
How bright is the room it will be placed in?
What is your main desire? All out performance, price vs. performance, screen size, etc.?
Personally, I prefer plasmas except in a very few specific instances, for many reasons.

There's a good place to start. It's essentially just like car audio.... read, read, read.
You've got a decent enough budget to get a stellar setup, but you've also got little enough information to let yourself get screwed into buying a brand name that isn't backed by service or performance, technology that is inferior or overpriced for performance, etc. If you wanna get taken, go out and buy the latest bling the salesman will sell you. Then all the fanbois here can pat you on the back and you'll feel great about yourself, but if you really want to get the best performance and value for your money, do the research and ask specific questions.
Good luck.
