Well, I went with a 42" plasma. I figured that would be adequate, and it's fine. I got an LG for $450. It's a dark room, so figured plasma was preferable to LCD/LED. I already wear glasses. so no way would I want an extra pair for 3D...
I guess George Lucas is reshooting most everything, for the Star Wars BlueRay edition... Which must be a new take on "do over."
Our Theater is adequate... We aren't paying for any TV service, and just on a roof antenna which is fine for the local flavors. I do notice a lot of football droppping off the network feeds (for New Years Day, the only game we got was the Rose Bowl) so will probably have to do something for Dish or Direct TV if it leaves completely. Which is a shame, since HDTV travels through the air and an antenna is enough.
How big are you going? 70"? Jumbotron?
Ace; I hid my BB gun from myself.
