Anyways, front projection for everyday use is a bad idea. Granted we are buying newer Panasonics LED now with like 30,000 hour bulb life. But you still need a good screen, proper room for it....trust me it adds up quickly.
This is one factor that ultimately pushed me off of getting a front projector system even after having designed the media room with ceiling connections for it (in two orientations on a long or short wall!).
The room isn't used daily, but cost, bulbs, sound, heat, the fiddling, just wasn't worth the hassle. Even less so with 70"+ flat screens becoming so easily available now for $4k; about the same cost for a high quality projector and screen, and our room can do a max. screen size of 80" before locating speakers around the screen becomes impossible.
Obviously other people have larger rooms and if you want a huge screen over 80", then sure, projection is still the only way to go, but very large flat screen technology is fast becoming the norm. Envision a 120" flat screen rollup OLED! No more projector needed. Has all the same features except no projected light issues.
It is coming.
