I'm looking to put together a home entertainment configuration that can be viewable in moderate light, but optimized for home theater experience. what have you guys experienced with these budget infocus projectors: what I've read: x2 - optimized for business presentations, NOT home entertainment use 4805 - front-runner, optimized for home entertainment use LP500 - just jumped out of nowhere at me...how does it stack up next to these other two? mainly just a super-portable unit? how about picture quality? I've heard some bad things. also...looking at building a screen (for budgeting reasons), what do you guys find a better solution...painting/mounting directly on the wall, or building a "stand-alone" frame. How bout the "Screen Goo", and/or DIY Theater? What about mounting an inexpensive screen (available on Ebay for 30 and claims to be optimized for great picture quality) to mount to the wall and frame? basically just looking to get the kinks worked out before I start this project. Thanks for your time and responses ps - I had links to all these items but it wouldn't let me post them. no biggie. thanks.
