Any recommendations for projectors?

We're looking to set up a small-ish screening room, 18x14 feet. Do you guys have any recommendations for a good projector? Found a thread where they talked about the DLA-Z1 from JVC and people having issues with Sony's VPL-VW1100ES (which is now discontinued). Also found some info about Sony's VPL-VW285ES which i guess it looks okay.

No color grading being done, but some comp reviews. 

Based in Canada.  Any recs and advice?

Thanks!

We are using the sony VW675es in all three offices. Along with a fixed frame stewart studiotek 100 Screens range from 10 to 15 wide

Yes, that is good in theory, but in practice, DCI implies P3, and P3 uses more of the blue portion of the light, of which there is less.  A typical rule of thumb for P3 output is that youll get about half the lumens.  Even rec709 wont give you 100% of the light due to the portion of the gamut being used.

And youre definitely correct that having too much light is also not ideal.  Even if you ND down the output, the contrast doesnt magically go up it stays the same or gets slightly worse.

Finally, in this day and age you likely will want to prep yourself for HDR.

Assuming a unity gain screen, to hit a specific ft-lambert target
divide the lumen output of the projector by the area of the screen in
ft^2. So if you have a 100 ft^2 screen and a 1500 lumen project, you
should be able to get 1500 / 100 = 15 ft-lambert, so enough for DCI
spec, but too low for a TV-style environment where you probably want
to be closer to 30 ft-lambert.

That being said "more is not always better": if you pick a projector
with too much light output, you may not be able to reduce the light
output sufficiently to hit your desired brightness target, and you
will end up having to mess with ND filters in front of the lens, which
you really want to avoid.

Agreed that 1500 lumens is not enough.  We have a VW1100ES (upgraded from VW1000ES) which is speced for 2500 lumens, and our screen is 10.5 wide (our room is 19x13x8).  Brightness with Rec709 is tolerable, but in P3 mode its definitely low.

Weve demoed much more expensive projectors (Sony VPLGTZ270, Canon 4K500ST, and a DPI Insight 4k LED) and a variety of different screen materials.  Where all projectors have a hard time is at or near blacks, and really its the curve down there that is often difficult to calibrate.  Simple things like stars are one of the hardest thing to project well.  If youre doing comp reviews, you are going to want accurate color else youll find yourself making incorrect decisions based on projector tradeoffs.
