Here's mine. I'm using an Epson Home Cinema 2040 running at 165 inches horizontally (nearly 14 ft).


It's hard to illustrate scale. For reference my ceiling is 8 ft and my kiddo is nearly 4 ft tall.
I bought this model primarily because of low input lag (25 ms) and $80 replacement lamps. 1080p 16x9, 2 HDMI and a VGA.
It's considered entry/mid level. If I had more to spend I'd go for the Sony VPLHW45ES. It runs $2k with $300 lamps.
There are only a couple of cons from my perspective:
Sunlight needs to be kept to a minimum. I replaced our curtains with blackout curtains.
Content must be HD. SD video is rough. 480p is decent if I want to play something older.
