Larry,
The Dell 2300MP is an XGA projector. That is, it is a 4:3 projector with a native resolution of 1024 x 768. In order to run wide-screen or HD material, it must rescale the image down to 1024 x 576. Not all that much better than standard definition in height.
If you zoom out the picture to fill a 16:9 ratio screen, you light will be sucked away too. Your pixels will also be enlarged.
As such, this is not an equivalent projector to either the Z3 or the AE700 in resolution.
Take into account that the AE700 and Z3 are somewhat optimized for the purpose of running HDTV and other "home theatre" programs, they are going to appear a bit better. I've seen what Sanyo does with their scalers and deinterlacers...they are pretty good for the home-theatre stuff. Panasonic's active iris and gamma circuit is also pretty impressive when set up.
I know I would have no problem putting either of these projectors up against the Dell (dude) with favorable results.
The Sanyo Z3 has street prices right around $2K (I know I would sell it for that and work for a dealer). Sanyo even has the Z2 still that is also optimized for Home-Theatre, is a 1280x720 projector that sells for under $1,500. Someone always has a projector for less...often that is what you get though...less.
Then again, the Dell projector does look like it has its uses and one might use it for Power Point shows for work and then pop a DVD on it for after work, I guess. Then again, Sanyo and others have projectors that can go head to head with the Dell with similar specs and price.

Steve..big, but obvious question on these two machines: One has the lumens of 1000 and the other as the lumens of 800, yet other LCD units have lumens up to 2000 lumens (being the regular 4.3 XGA units), would this lesser lumens of the two WXGA machines have noticable reduction of display on the screen than if one used the 2k lumen units?
Also, if one used the WXGA units, can these still be used in 4.3 display when featuring regular full-screen movies-just might have to "zoom" up the image if one has full actual adjustable maskings on their home theatre screens-both vertical and horizontal?
Granted, if one only has the vertial masking adjustments, then the 4.3 image size would be smaller and not have to be "zoomed to fit," so to say.
I'm asking these questions on possible construction of a "home theatre" system in my home. If one is going to do "home theatre" why not go all the way and do it right?
Myself, I'd rather use LCD, than DLP due mainly to the "rainbow" effect of the colorwheel and the single chip display. Maybe, down the road a few years DLP units will have the 3 color chip array where no colorwheel is needed (like the big Christie and Barco units for theatres), and at a reasonable price for home usage.
thx-Monte

Kodak's latest pre-show HD digital projection system uses a 3-chip DLP projector:
Another Really Long Link
quote:
The Kodak Digital Cinema system includes a package consisting of proprietary software, as well as hardware and services to prepare, distribute, and display quality pre-show advertising through feature movie presentations on theatre screens.
The full system is being demonstrated on multiple cinema screens at ShoWest at a special event prior to feature presentations attended by hundreds of industry professionals. "It's important for us to demonstrate our system in a real world environment to some of the most demanding audiences," Doeren says.
For the pre-show demonstrations, Kodak is using the new three-chip DLP high definition ScreenPlay 333 projectors from InFocus.
"High definition projection is the next step for pre-show presentations," says Doeren. "On the InFocus projectors, the images are brighter and sharper with a greater range of contrast and more color saturation. Combined with surround sound, they make everything, including concerts and other events, a more enjoyable experience. HD images on our system have a crispness and depth that seem to jump off the screen."
Doeren emphasizes there is still a difference between high definition and motion picture-grade quality. For feature presentations, the company is demonstrating the new Kodak CineServer, which is compatible with a range of digital projectors up to 2K resolution. Kodak is using the Barco 2K DLP projector to show trailers and motion picture content at ShoWest.

By teaming with Kodak and CSM, the world's largest independent provider of digital pre-show presentations, InFocus projectors will be a part of Kodak's new high-definition pre-show capability. CSM is using the Kodak system to raise the standards for the unique programming they provide prior to feature films in movie theaters nationwide.
InFocus will provide high-definition digital projectors with customized lens options to complement the Kodak Digital Cinema system. The specially-produced InFocus ScreenPlay 333 projectors use three DLP chips by Texas Instruments and provide captivating images to set the stage for the feature film presentation. Built from InFocus ScreenPlay engineering, the ScreenPlay
333 uses this legacy to create a professional product ideal for the needs of public cinema.
