I've seen lots of discussion on the different technologies, maybe this will help a little.

Information taken from Toshiba fall/winter 2002 catalog. I used Toshiba because that is what I had on hand and what I own. Prices listed only for comparing the technologies, are approximate and were taken from the web. All the sets listed are top of their lines and have similiar features except for the technology. All have DVI except the Sony LCD.

CRT RPTV57 inch HD Compatible Wide Screen CRT RPTV $2,700 (These sets will burn-in)

LCOSThe acronym LCOS stands for Liquid Crystal on Silicon. Liquid Crystals are coated onto a Silicon Chip, which uses a reflective (aluminized) layer. As compared to standard LCD Chips (see definition below), this reflective design greatly increases contrast, and eliminates any dotted "screen door" effect. As it is a digital device, LCOS technology also eliminates any chance of burn-in.

57 inch HD Compatible Wide Screen LCOS RPTV (Three LCOS chips) $8,000 (These sets will not burn-in)

PLASMAA Plasma Display uses tiny pockets of plasma gas to create thousands of pixels. By eliminating the standard CRT scanning process, large Plasma Displays can achieve a depth of only 4 inches. This allows Plasma Displays to be put on a stand, or hung on the wall like a picture.

50 inch HD Compatible Wide Screen Plasma Display $9,000 (These sets will burn-in)

LCD TVThe acronym LCD stands for Liquid Crystal Display. These thin, flat screens were first used as Laptop Computer displays. Most LCD RPTV's utilize three LCD panels and a single light source that is replaced when it ages (100 watts in the case of the Sony below).

60 inch HD Compatible Wide Screen LCD RPTV (Sony) $5500 (These sets will not burn-in)
LCD HD Compatible Projector 16:9 1280X720 Contrast Ratio 400:1 $5,000

DLPThe acronym DLP stands for Digital Light Processing. A major component of DLP is DMD, or Digital Micro-Mirror Device. This DMD chip employs upwards of 1.3 million tiny mirrors to create a picture, much like the pixels in a CRT based device. Most consumer DLP products employ a single DMD chip. Another major component of DLP is the color wheel which is used to create a full palette of colors. As it is a reflective techonology, DLP provides high brightness and high contrast without any possiblity of burn-in.

DLP HD Compatible Projector 720p Contrast Ratio 1400:1 $10,000 (These projectors will not burn-in)

I did not include Direct View CRT because they are not available in the sizes we are talking about here.

I have a basic understanding of which 'looks best'. Perhaps those with more experience can help us out.

Thanks,
Lee
