I've been following the JVC RS45 thread, and although it's a fairly bright projector, I don't think it has the lumen output to light up a screen that big, especially once the bulb ages. When you throw 3D into the equation, the projectors you mention won't even come close to lighting up a 166" wide screen. I think for a screen that size with a gain of 1 -1.3, you will need to look at a projector that is a lot brighter than the JVC, Pannasonic, or Epson models. It appears that the new Sony VW1000 will adequately light up that size screen, and for sure the Sim2 Nero will work, but you are looking at spending a lot more money on these projectors than the JVC and Panny. I'm in the same boat as you though, I want a 160" wide 2.35 screen, but I'm not having any luck finding a projector under 15K that will give me the kind of brightness I need. One possible exception might be the BenQ 7000. In torch mode it might give you the lumens you need, but the native contrast on that projector is much less than what I would like.
