I am building my first Home Theater with a dedicated room. I have done a lot of research and still am not sure which brand to go with. As far as price, I am willing to spend around $8000. I am leaning toward the Optoma or InFocus brand. At first I was going to go with the H79, but I found out the new Optomas are coming within a few months. So I decided to buy the HD7300 when it comes out. 1. Is this a good choice given my budget? 2. It says it features an external video processor. I can't figure out what that does and where that goes if my projector is going to be ceiling mounted. 3. What is the best screen to have when the room has complete light control? Thanks in Advance
