Here's my dilemma. I know that a better quality screen will often provide you with a better picture, but I'm not sure if I should spend $900 on a good budget projector (like the BenQ HT1075) with a $1100 screen, or spend $1700 on a better projector (like the Epson 3500 or 3600e) with a $300 screen? Besides general PQ, I want the best possible contrast I can get for $2000. Should the focus be the projector, or the screen??
