If you have the space, you can get incredible deals on 3 gun CRT projectors. Systems that brand new were $35,000 can be had for a few hundred dollars.

No. RGB component cables.

Though - his main consideration is picture quality.*

8350 puts out a great picture, but the HC4000 is cinema king.
Depends on your space - my personal experience is that it is very easy to set up without lens shift, and the set up is something you only have to do once. Unless the room shape is very unique (unmovable poles etc), lens shift is not that essential.

What, you mean those light bulbs in the projectors don't cost $600 to manufacture?

I've been reading up on the 3-gun CRT projectors, they are very interesting. Most attractive in their arsenal is the fact that you don't get the "screen door" effect that is a given with DLP or LCD projectors (screen door being the dark grid that makes each pixel stand out). If you get the right one and set it up correctly, they CAN do 1080p. The blacks are obviously FAR superior to other setups, and contrary to popular belief, the tubes last a very long time. They should not be used for desktop setups as static images will burn in, and they are very heavy and require stationary setup, so no moving it once its set up. But if a dedicated home theatre setup is what you're after, it would seem that a CRT will make your GH2 footage look VERY good.

Mentioned by many who have both, is the reality that DLP and LCD projectors are built as disposable units. If one of those goes bad outside of warranty, it is usually cheaper to buy a new unit, whereas CRT projectors were built to last, and to be serviceable.

I don't have one, or space even to set one up . . . but I will be checking into them further when I do have space and money. LCD and DLP images are too sterile and digital for my taste.

If you are considering a projector for home use, make sure the fan noise is not intrusive and the keystone is sufficient for placement. I've been looking for one with enough lumens to use in a larger room, for example to present a small video festival.

The DLP and LCD pj's I've owned have all been not worth keeping once the bulb goes and the bulbs don't last particularly long either. CRT's on the other hand will work until the end of time. They're not as bright, so light control is critical, but the image is amazing, like you say, jet black blacks, zero artifacts, extremely filmic. They're bulky though, I used to own a NEC with 9" guns, it weighed 200 pounds! I had to build a truss to hang it from. But I ended up liking the industrial look of the truss.

At 1080p projection, SDE is not really the issue it was anymore, for either technology. The RBE of dlp though, is still noticeable to a few at 4x speed. For lcd, the problem of RGB panel convergence is gigantic. Most sold have misaligned convergence by a pixel or more. This can significantly reduce perceived resolution. While lens shift relies on quality optics, it is still better than keystone if you are forced to place the pj to the side of the screen.
Many factors.
