Send one of the salesmen at AVS an email or call on the phone and request quotes for all the projectors / screens / HE lens / etc that you want. You'll be pleasantly surprised. I buy just about everything from them anymore. They are authorized to sell just about every brand out there. Plus, they know the products they sell and have a great return / exchange policy.
On the curved screen, I doubt you'll be able to find bulk silver material with a gain of 3. Silverstar is the only other high gain silver I am aware of, and their flat, rigid screens are well over 5 grand and take up an entire van to ship them.
