I have a room with a slanted ceiling. The short wall is 100 inches tall and is behind the couch. The tall wall is 136 inches tall and I project on it from about 48 inches off the floor to 136 inches. There is a projector shelf on the back wall a few inches below the ceiling which puts the projector lens pretty much in the dead center of the image vertically. In theory this is great because with a lens projecting straight out I don't need any lens shifting or keystoning. Just one problem - many projectors have a build-in vertical image offset and they don't always tell you what that offset is in product listings.

I've been projecting from my old Panasonic AE900U great for years. It's dying, so I replaced it with a Benq HT1075 (similar to the W1070) and was quite surprised to discover a severe image offset making the projector only suitable for projecting from a coffee table (or upside down from a flat, as in not-slanted, ceiling). Unfortunately I am going to have to return the HT1075 since it's pretty useless for my application. From what I can tell online, I won't fare any better with the Optoma HD26.

Are there any "straight shooters" out there in the under $1500 range that are good for 3D?

Epson hc3000, 8345, the Panasonic 100u are all straight shooters for less than 1500.(only the hc3000 is 3D) The Panasonic ae8000 and Epson 3500 are both at or slightly past the 1500 dollar mark. The best 3d players are the Epson hc3000 and hc3500. (They're both so bright, it seems like they were purpose built for 3D)

I don't quite get it. Your image bottom is at 48" off the floor and your image top is at 136" ? That would be an 88" tall image, or a 180" 16:9 image. That seems unlikely with an AE900u.

Can you clarify the screen size and the distance from lens to screen you are looking for ?

The room length is 19.5 feet, minus the depth of the projector and cable clearance, so about 18.5 feet from the lens. Screen size ends up approx 156 x 88 inches.

OK, you will be very limited in choices of projectors that are bright enough for a screen that size.

The 1075 has only a few inches of vertical offset, but I don't understand why you want to return it. Since the bottom of your image is at 48" off the floor, and that is above the heads of the viewers, why not simply set it upright on a 40" tall cabinet or shelf on the back wall ? Many people would love to have such a simple mounting option. If you really want it mounted high, then the Epson 3000 or 3500 seem like the only other options with the brightness in 3D for a screen that large. The new Benq HC1200 also has the throw and brightness, but is not a straight shooter.
