Actually, you will probably get more relevant information in the CRT Projectors forum.
I watch HDTV on a CRT front projector and a 92" 16:9 screen, and I'll tell you it's much better than my 61" HDTV, and much much better than DVD. With the right CRT projector the image can be even sharper than a rear projection HDTV.
If you're going to get a projector, get a Marquee. You can get a used one for about $3000. I have one, and never regretted it.
