I built my own screen using nice oak 1 x 3's and corner braces. The material I purchased was Dazian Matte White Cinema Projection material that is secured around the screen using industrial stength velcro from Home Depot. I probably have about $100 or so wrapped up in my screen. There are also other options for DIY methods like Parkland Durotherm-Lite Panels you can find at Menards and other home improvement stores.

My screen is a 2.35 aspect ratio and is 51" x 120".
