Yeah, as mentioned the one thing I had to do was adjust it due to the closeness of the Sony's mount holes. I had to slide the small "L" shaped pieces that attach the mount's arms up so that the arms weren't against the projector as much, and I could get to the screws to insert them. You'll see what I mean when you get it. I've mounted 5 projectors with it so I got to know it fairly well, and the Sony was the only one with any challenge. (I think they want to sell more of their $800 mounts. )
jrlnc, congrats on your purchase. Sounds like you did some good research and used previous experience. I never had an LCOS RPTV (though I had looked at them in the store), but what swayed me was getting to demo an older VW60 SXRD model. Knowing that the HW15 was supposed to be brighter and have better blacks made it pretty easy. I've got nearly 400 hours on mine in under 3 months now - I have NEVER put that kind of mileage on a projector before, so that says something! Even with the Optoma HD80 I had which was very minimal on rainbows, a fatigue would set in that doesn't happen to me with the LCOS technology.
