It doesn't matter how bright a projector you use, it won't be usable with lights on. You'd need an ALR screen and even then the image is poor. I had the funds for a "pro" projector as you say, but I went with a TV because projectors are inferior for picture, only good for size vs cost. As before I don't value contrast from darkest black, only brightest white, as in I value contrast where the contrast comes from brightness rather than darker blacks. High lumens are not available in home/consumer models, they list 2000-3000 lumens and the higher models may go upto 5000, then the reviews will say in "best" mode it is less than half, if you want to use that mode. Brightness in consumer projectors has increased but not enough to be bright enough in a dark room, at least for me. I'd need at least 5000 lumens for a dark room and 100" inch screen, if you increase the screen size then I'd need more. No one who is considering the Sony or JVC will ever consider the Epson, as you say Epson is a value proposition. No projectors won't ever replace TVs due to inherent inferiority of the picture, need for darkness, degradation over time, and specific install needs. People use them because they are again value for size, something people trade if they can. I only shifted to a TV because a 85" TV no longer costs a silly amount of money like it used to. If the TV was still very expensive I'd still be using a projector, in the end it is value vs size and where someone falls on the spectrum.
