Seconded.  LCD even at native resolution, I still get banding due to 
MOST panels itself is limited to 6 bits, 8 bits panels is out there 
but diffcult to find.  I rather want 10-12 even more bits.
Money did speak too, I had to replace my much loved samsung 17" flat 
CRT (really dim after 4 years) with this less trilling Samsung LCD 
19".

As repair shop, I know the range of watts, LCD does have limit where 
you can see benefits.  24" is about the limit for efficient.  
Anything larger, use TV CRT for entertainment beyond 36" go rear or 
front projector, the 3 CRT proj have least watts, for large than 60" 
DLP or LCD.  Remember to keep your cooling system clean for DLP and 
LCD for lamp life and also more important on LCD life especially 
this.   One byproduct is you have to be careful with HID lamps is 
they contain mercury and it is not fun if lamp explodes, common than 
you think!  LCD do contain mercury in the lamps fluorscent tubes.
There is a one that is now available is DLP with LEDS in place of 
lamp and I rather go with this, efficient and safer.

 Plamsa and LCD larger than 27" simply consume too much watts but 
this trend reverses above 60". Large screen size with one len (DLP 
and LCD) and very short depth have bad issues with illumiation 
distribution, I see this all the time with 60" and up.

> Perhaps I just haven't found a good source for CRT screens....

Alas!  I still want a CRT, as LCD is not 100% there.  I'm watching on 
technologies like SED, OLED and more recent ones in research and on 
market.
