Wrong place for this, and I don't know much about Televisions....
what kind of space do you have? You could get a projector and screen within your budget......THINK BIG
You'll need to specify a size though, if you want a better recommendation.... Pioneer makes great Plasmas, Sony makes great LCDs.... There's the new Viera, and samsung is highly regarded.....
There's a t.v. for everyone's budget, and $2,500 will get you a nice one these days!
