I tried the Mits HC4000, and others, before I settled on the W6000. I have a living room setup with ambient light, so the Mits didn't stand a chance. But even at night, I felt the image lacked pop. We love the performance of the w6000 and have nothing bad to say about it. Our unit is very quiet, and the iris noise is almost inaudible. We use it as a tv replacement so we have already racked up the hours with no issues.
There are several vendors, including Amazon that are currently selling the W6000 for $1359. However, Amazon charges sales tax in NY, so I had to look elsewhere.
I found that Overstock.com has the W6000 for $1359.99. When I was on the page, there was a 5% off banner in the right sidebar with a 2 hour timer, and when I added the W6000 to the cart, the total was only $1291.99!
