Hi, I've narrowed my choices down to these 2 due to budget (under $1200) and my intended use (99% of the time for playing DVDs). I will be buying a motorized drop down screen (about another $500). Between the 2 projectors above, what would you recommend? I will be watching movies (lots of action and drama) after dark only, so lighting control is not an issue. I've found the SP4805 for $1099.99 and the H31 for $1079.99. So price is practically a wash. Thanks!
