jgvp, you don't _need_ to spend tens of thousands, fact is a REAL HD HD2 projector can be had for under 4k (not hd2+), while it doesn't have inredibly good contrast, it's pretty damn good, and you get more than 2x the pixels the 4805 has... or if you really want great contrast (same resolution as and hd2 though) you can go get yourself a sharp 12k for about 10 grand. but lets recap here... if you want PQ comparable to your sony GW2, then it gets a whole lot easier.. get a Z2 or an AE500, and if you really want allmost identical PQ just go get the sony HS20 for about 2.5k. (i think it should actually be better)
This PJ was blown out of proportion in the older threads, i'm sure it looks just fine, but it's still missing what made me go to "the big screen" in the first place, and that's the ability to see more detail as you go bigger (i blame my IMAX experiences for that, now THAT looks sharp, not just "bigger"!)
i'm not a huge fan of soft images, and the bigger you go with low res material, the softer the pitcure will seem.
i'm still sure a lot of people will be very happy with this, it's just not for evryone.
