plasma versus lcd

Sony makes a 60" projection LCD. On an in-store closed circuit demo, picture quality was, to my eyes, better than cheaper plasma's and as good as the better, newest plasma sets. Street price for the 60" seems to be around $5k, which is about what the 42" plasma's seem to be going for. Since even the street price on the 60" plasma is north of $15k, the lcd is a comparative bargain. I also would be interested in some technical analysis and comparisons of the two technologies.

Any good web sites to compare or get info in general regarding LCD/Plasma technology and brands?

Wow lots of questions, but still no answer. So since we are on this topic anyone have any opinions of the new Samsung DLP rear projections? I mean a 50 inch rear projection that weighs less than 100 lbs is only 16 inches deep, and doesn't suffer the same viewing angle requirements of a standard rear projections seems very promising. Am I missing something?

I own a Sharp 32 lcd and the Sharp 50 inch plasma. My problem is that I live up in the mountains at about 7500 ft.
Up here the Sharp plasma, (and other brands I tried) buzz like crazy. Its really a pain and its really quite lound. Where as the LCD is dead quiet. Plasma does seem to have to a little better blacks, but the buzzing is driving me crazy. If you are at sea level....never mind.

Here is a link to a discussion forum with more links to the issue.

it may help, or confuse even more. BTW, I assue a difference between projection LCD and flat screen LCD. I assume the posted question refers to flat screen LCD.
