I just moved into a new house and I lost my dedicated home theater from my old house and now have to share a space in the basement that will have a ping pong table and a bar (not soo bad so far). There is a walk out porch so there is ambient light coming in, but it can be controlled.
I have a wall space that can fit my current screen which is 9', but I have a sofit to deal with and a column that forces me to go just under the soffit for the screen if I go that route. I was considering going with the Epson 5020e, however, after reviewing the space and my usage I'm wondering if a 70" LED TV would be a smarter choice because of usage and lighting.
I use my current projector a lot for watching casual tv and movies combined. No one is a clear winner there.
3D may be cool to have, but, its not something I plan to use heavily.
In the end I can control lighting, but in the day if you are watchin a game or something, i know the wife will open the shades all the time.
I like having a 9' screen though.
Also with black friday deals on 70" sharp being $1799, thats a hell of a deal for that...
