The InFocus IN83 is killer. It has great color reproduction as opposed to the oversaturated colors of Epson, JVC, Sony. It's bright enough for people to watch with the lights on and you can turn down the brightness for night time viewing. For watching sports it kills those others with it's pixel response time that is hundreds of times faster.

By smoke do you mean the RS1 is much dimmer, has lower ANSI contrast, has oversaturated colors, and is susceptible to color decay?

Just go read the magazine reviews that measure ANSI contrast (black and white at the same time). Widescreen review measured the JVC (supposed 15000:1) at nearly 1/2 the contrast of the lowest DLP projector they ever measured. At their jacked 25000:1 maybe they've caught up to DLP?

Mis-type from above - Should read: At EH Expo a JVC representative even said to an audience that it was NOT ideal for rooms with ambient light.

Everything has pros and cons with projectors.
The JVC RS1 and the Mits HC5000 have the typical problems that all LCD/LCOS have. If you like watching HD sports, neither is preferred. The pixels don't respond fast enough and the motion blurs. They also have color uniformity issues. Put an all white image on each and notice the red and green tint to different sides of the image. It is also apparent with scenes with sky. LCOS is also "soft" (the pixels are blurred together). This is great for watching movies as it appears film like; not so great for watching broadcast HDTV. All of this is why you'll never see LCD/LCOS manufacturers demo HD sports or put up a bright all white (or light) image.
Lastly, ask how long you plan to have it. LCD and LCOS break down beacause of the high heat produced by the lamps and start to have blotching on the screen. This state is unrecoverable.
LCOS is good for dark rooms but because of its lack of brightness suffers with any ambient light. At EH Expo at JVC representative even said to an audience that it was ideal for rooms with ambient light.
If you can get the opportunity, have a dealer put a 1080 LCOS, LCD, and DLP side by side with all different kinds of content - bright movie, dark movie, HD sports in both 720 (ABC/FOX) and 1080i (CBS/NBC)- in a similar lighting environment for your theater (pitch dark or light in the room) and then make your choice.
I think you'll quickly see why the highest end brand in the game, Runco, uses nothing but DLP as it has the best "all around" image. DLP is by no means perfect either, but today offers the best of all worlds.
