I'm a huge fan of the Sanyo projectors for the commercial environment, but almost all the larger and nicer venues have started to move to Digital Projection as their standard. The high end 3-Chip DLP models from them tend to be about twice as much for similar specifications, but typically when you have a need for 15,000 lumens, it's because the screen is in a $1,000,000+ facility, and they want that real added quality of 3-chip DLP vs. LCD.
Not exactly a home use product unless you don't have good light control in your theater, and DO have a dedicated projection room. I installed their older PLV-WF10 which was a 1365x768 projector into a room about a year ago and the fan noise on that sucker was ridiculous in the room. Very distracting and unwanted.
We just had a room that called for the WF20 (an upgraded WF10) which I changed out for a Sanyo 1080p model, but then changed to a Digital Projection model. The difference in noise output was truly remarkable as the DP is barely audible in the room.
As well, the 6,000 lumens delivered on a 100" 16:9 screen was completely pointless. With a 1,500 watt halogen light shining on the screen we still had a perfectly usable image. It was ludicrous! We dropped it into single lamp mode and it is more 'typical' for that size of screen in that environment, but I would happily use DP again as I continue to use Sanyo.
Unfortunately, the world is moving away from projection in the commercial environment in favor of large format flat panels.
Still want to install a 150" Panasonic. That sucker is inspiring to see.
