After researching and web searching I finally treated myself with a budget home cinema. pta 300 projector for £1200, maratz 4300 av processor for £199, Mordaunt short premiere speakers for £249 , toshiba sd 300 dvd player (Multi region) for £79 and connected with Monster cables £100 (home cinema kit from comet) and the 7ft electric screen from E Bay for £155.I am looking for a ceiling mount and 1. I am not sure where to buy from. 2. Would the picture quality be considerably deteriorated if I project from the back of the room to much wider area than the screen itself (buying a bigger screen). I believe the ratio of screen size and viewing distanc is 6. my room size is 25ft-18 ft. In view of the short throw distance of the pta 300 at present I am projecting from a very short distance( from the table top). Comments and advise please.
