Shadowwalker, which projector do you have? Do you want a white or gray screen? One very popular DIY screen is to use blackout cloth(it's white) from any fabric store, and staple it to a wooden frame you build(about $40 total). Or you can paint a sheet of Medium Density Fiberboard, $30 including paint(This is what I did for my screen). Or you can buy a 4'X8' sheet of Parkland Plastic wall panel, or Doable Board and hang it as is(they're both white). But they're hard to hang because they're thin. There's a lot of info at Avsforum.com in the DIY Screen section.
