So does anyone have a Epson EH-TW5600?  for $1200-1400 seems like pretty good value.  

Anything to be concerned about?

Anything else at this price point to consider?

Would a BenQ TK800M 4K HDR 3000 ($800 dollars more) be that much better on a 90 inch screen?

Main use

Completely black room (walls and ceiling).  Downloaded movies and TV mainly at 720p, and possibly new xbox if allowed to buy one around Christmas.
