Maybe add the viewsonic pro8200 to the list to check out. I use it for gaming, and social football games, and tv viewing. When it goes on sale for a little under 700 dollars, might be cheapest 1080p that is also decent multipurpose PJ. It comes with 20 watts of internal speakers, and handles different types of lighting conditions. Includes 3 year warranty that the other ones don't. And long bulb life and cheap bulb replacement is also one of the best in this price range. Low RBE, and low gaming lag of about 15ms.
It has been out for a couple of years and it's proven to be pretty reliable. Sometimes it takes a year or so to find out if a PJ has problems in the forum rooms and this model seems to be holding up well. Best way to find out is check the forum rooms of the models you are interested in and see if a number of people have the same problem. And look at amazon/newegg user reviews.
I'm past the 1 year of ownership, and have 2 more years under warranty, other PJ's that only come with 1 year warranty would make me nervous after 1 year if something went wrong if I didn't get the extended warranty on those models.
If you want 3d the benq w 1070 could be good, it's new, so don't know how it will hold up and only comes with 1 year warranty. I'm thinking for me, they came out with 4 firmware versions so far, in only a few months, hard to know if another will be coming or not. And you have to send unit back to benq to have them put it on. If I was to buy the w1070, I would wait 6 months to see how the forum looks, and if bugs are out of it.
Maybe the other guys can give you a few other models to also check out and research it. If you do get something like the pro8200 , you are not out a lot of money, and you could in year or 2 get a 4k PJ, or laser/led model and use the pro8200 for den/bedroom/travel.
