[XCSSA] Purchasing used 1080i TV advice

[X-otic Computer Systems of San Antonio]

How easy is it to move?

Could be any number of "internal projection" technologies:

CRT
LCD
Light Pipe

CRT projection has good qualities, but often looks dim unless you  
have darkened room (as you should have anyway for watching tv, not  
totally dark, but 10% of maximum screen brightness).  Also they are  
HEAVY!  For this, check if brightness level and color are  
satisfactory to you, and can handle the weight. Also check geometry,  
focus, convergence of colors, background uniformity, etc.

LCD projection (and non-projection) have somewhat inferior black  
level, but appear very crisp and bright otherwise.  Every year the  
LCD black level gets better, still no where near CRT or Plasma.  They  
are pretty much all direct-view now since LCD panels have gotten so  
cheap, no point in bothering with projection anymore.

Light Pipe similar to LCD projection

For LCD and Light Pipe, stuck pixels can be a problem (though there  
are pixel-unsticking DVD's that exercise the display)

How big is it?  Nowadays LCD displays 52 inches and under are  
reasonable, and 32 inches are cheap.
