I hate the wobulation on my 73837. It softens the picture too much. I'm done with fake 1080P. Last weekend I installed a front projector in my living room (BenQ W6000, 110" Da-Lite Da-Mat HC screen), and it smokes my Mits. I'm using cinema mode with the lamp in eco., and it puts out plenty of lumens (less than my Mits., which was at 40 ftl, but plenty bright). The only change I had to make was installing a double curtain rod on the sliding door that holds both the normal curtain, and a blackout curtain (Wal-mart). With this, daytime viewing is just fine. If you can do it, there are a few front projectors/screen combinations that will work for living rooms with some ambient light.
By the way, I'm only putting this out there because if someone had told me about the W6000 when I bought my 73837, I would have bought the W6000 instead. At the time I just blindly believed that a front projector wouldn't work in a normal living room.
