I am in the planning phase of building an additional room as an upstairs in my house and turning it into a theatre. I currently have a Mitsubishi 65" Widescreen RP TV. My question is this. What kind of front projector/screen can I get for a medium/large room that is going to give me a picture as clear and crisp as my RP TV without breaking the bank on cost? I know that this is probably as ambigiuous as asking what the best speakers are but I'm just looking for suggestions based on your setups. I've seen posts about the Infocus 4805, is this picture going to be as good as my mits or will I be dissapointed?
