When it comes to choosing a screen, the first consideration is the type of screen you want or even need. If the room where you are setting up your home theater is large, then you will have to have a home theater projection screen or maybe you just want one anyway.
I, personally, like the idea of having a drop-down screen, but sometimes you have to have one even in a modestly-sized home movie theater. It would convert your living room into a home movie theater. Imagine: you recline in your chair; click the remote and a screen drops down; click another remote and the lights dim; click another one and the film commences!
However, if you prefer a television screen, then you might consider buying a new one. They say that a 27 inch screen is adequate, but I do not think it is. I really think you need 48-60 inches, but then I am a 50 something year old and my eyes are definitely not what they were.
If you are buying a new TV for your home theater, I think you should aim high. HDTV is upon us and since February 2009 the USA is committed to High Definition. So, I would make sure that your new TV is capable of receiving it. Then I suggest that the new home theater screen be a flat one to reduce the annoying glare that could ruin the experience. (This could be another reason for opting for a projection screen).
Then you should ensure that the new television has enough input and output sockets for the equipment you plan to use and youre done. So, to summarize, I would go for:
At minimum a 27 inch screen
A flat screen
HDTV compliant
Enough input and output plugs and sockets
Satellite compatibility
I would definitely get a receiver which is already satellite enabled, because it is the future or even the near future. If you get a satellite TV connection you will have access to HDTV downloads which you can watch on your new home movie theater set-up whenever you want.
