I haven't observed/noticed any crosstalk or ghosting when watching 3D on my XV-Z17000. But maybe I don't know what to look for...and don't anybody try to educate me!

I'm blissful in my ignorance, apparently.
The only shortfalls with the XV-Z17000 are, IMHO:
1. Placement/alignment limited due to fixed offset: no vertical or horizontal adjustment.
2. Fan is noisier than other models (seems like it is twice as loud as my BenQ W5000, for example). Not really noisy, but I can hear it when I stand at the side of the room and there is no other source of noise. It does not seem as loud when seated (below and forward, obviously).
Everything else that may be a compromise/limitation is the usual part of DLP vs LCD/LCOS chatter: black levels vs image brightness, rainbow effect (I don't see it) vs alignment issues, etc.
I was all set to buy a JVC RS-40, but the availability was poor and I determined that an XV-Z17000 would fit perfectly in my room. Since I had the BenQ W5000 already I was familiar and comfortable with DLP tech (no RBE, etc), so I just switched orders with AVS.
As always, the thing that annoys me the most about projectors is knowing that I'll be spending a not-insignificant amount of money to replace the bulb someday. So LED light-engine technology is the only thing that will make me want to upgrade in the forseeable future. Well, 4K sources/displays, better blacks, and higher brightness might tempt me...
