Hey Sam, I have a Samsung LCD big screen TV. Have had it for like...nearly 3 years now. You're gonna love yours, Samsung TV's are so awesome :) I like that you get a 3 year warranty with Samsung too, compared to the 12 months Sony gives you. You know it's going to last you for ages too because...well, you know how much TV I watch :P
Sidenote: How cheap are TV's these days?! I got a good deal on mine, and it was $1800 or so! Nowadays, like you said $400 for yours. It's mostly due to 3D TV's being released, but I prefer the good ol' 1080p 2D :) 3D is more of a "let's go to the cinema and watch a 3D movie" when you're in the mood to strain and hurt your eyes.
