I plan to have a plasma TV and projection screen on the same wall: the plasma for daytime (lots of windows) and regular use and the projector for 'movie night', etc. One has to get out of the way of the other, so my plan was to have a retractible projector screen drop in front of the plasma. But it seems that roll up screens can (do?) get wavy over time, and they are not so cheap anyway. So, I thought, why not have the plasma drop into a cabinet? It seems it could be a wash cost wise if I do a DIY screen (like Goo or something) and build the cabinet myself (I had planned to for that location anyway). Am I mad? Should I just use a drop down screen and not worry?
