Nothing against Stace's setup but as he said YMMV. I too have a centerstage XD screen that is 144" wide (165" diag 16x9) and there is no way that a JVC HD250 in low with 850 hours would be acceptable brightness for me. That projector is likely putting out 350 lumens in low at 850 hours. I run a pretty bright Infocus SP8602 and at close to 800 hours I was down to 525 lumens and had to buy a new bulb as it was simply too dim.
I will make some recommendations based on my experiences with front projection and big screens. I started with a 120" diag 16x9 screen and I can tell you that I would never go back (and that includes giving up 3D).
1. I would argue that your room will be very important to your ability to light up your screen to an acceptable level. Therefore your room must have full light control with dark walls, ceiling, and carpet. I went all black with no windows and it was the best thing I did for the perceived brightness on my screen. If you do this you will only need 10-12 fl max when bulb is new and your projector choices just went up dramatically.
2. If you take care of the room as described above and are most concerned about 2D then most of today's brighter 3D projectors should be fine and this includes any of the JVCs (you will likely be on high lamp mode after about 300 hours though due to lamp aging) and I would highly recommend the Sony 30 or 95ES as they have proven to not loose near as much brightness as the bulb ages and the bulbs are very cheap to replace if you need to replace often. Also consider the BenQ W7000 and the Panasonic 100U (if willing to give up 3D)
3. 3D is not very realistic on bigger screens with no gain so as long as you focus on 2D you will be ok, and you can play with 3D when the projectors bulb is new and bright. I personally don't think 3D is worth much so not having it doesn't bother me and I know even if I did have it, I wouldn't use it very often anyway. But it all depends on your priorities.
4. Be prepared to change the bulb at least annually or every 600-800 hours to maintain acceptable brightness levels depending on your taste. If you can stand a dimmer image as Stace has grown accustomed to then all the better and you can save the money for lamp replacements.
