I am seriously considering the Panasonic PTAE100U LCD Projector ..... Heres what my situation would be ...... 12-15 feet whether I am laying down or sitting down ..... Screen will only be between 70"-85" 16X9 diagonal DIY. Light Gray ( already have plans on making the screen, also purchaed materials ). Screen will be suspended from vault in room. Projector will either be sitting on unit behind bed or sitting on stand/table in front of listening position. I have heard of screendoor from this unit and maybe contrast issues. But room WILL be pitch black. And it is only a 75"-85" Screen. How big of a factor will screendoor be on this unit,on that size of a screen? (Ive seen most complaints of screendoor form folks with 90" and above screens.) How good will the Denon dvd1600 be on this projector with this size screen? Whats the cheapest I can get this unit for safely (i.e. possible warranty work etc.)? price on replacement bulbs? Thank You!
