I have recently commited to building a HT in our basement. I have a rectangular room that is about 15 feet by 23 feet. i am ready to purchase a sony vplhs20 projector. If any of you have suggestions about this, i would very much apprectiate it. I plan on purchasing a da-lite da-mat 106 inch perma screen. how dark should i be prepared to paint the walls and ceilings in this space? is a light colored floor contrary to this set up? I have a budget of $5,500. Thanks for any input you have.
