Check out the BenQ W1070 thread. I had one for a while and really liked it a whole lot. For $1K, you get a pretty fantastic projector.
Not sure how it compares to W7000 (never had one) and I didn't get a chance to try out the 3D (wish it came with glasses) but the
PQ is pretty top notch, especially when you consider the price. I ended up having minor issues with rainbows (sigh) and liked the
Epson as an alternative, but I'd probably still have that projector otherwise. Anyhow, check out that thread.
