My first projector was purchased in 2006. I couldn't really afford a top level screen at the time, so I bought some good screen material and made my own, which was 96' X 51'. It served well, but I always knew I needed a better screen. No matter how good your projector is, the screen is the final arbiter of what you see.
I decided on Stewart for obvious reasons. Quality reputation, and top notch service and products. I have complete light control in the movie room where the screen was being hung, but I did have to make some minor physical adjustments to the space. Otherwise, it fit my space exactly. Following the instructions to the letter assured a mainly stress free experience, and within a couple of hours my new screen was up and ready. The difference is immediately obvious, and now I wish I had taken the plunge years ago. Trevor, at Projectorscreen.com gave me the help I needed in terms of choosing the best screen for my needs, and the ship time was actually less than originally stated. I don't regret anything regarding the experience; it was professional all the way.
