Although the screen on those is small, the CRT can be quite long (Either 
mounted along the video camera body, or across it, with a mirror to 
reflect the screen into the eyepiece).

> tiny?  What about a Sinclair Flat Screen TV?

Be warned that that is a typical Sinclair design with some very 
marginally-rated components (the HV rectifer diodes are nothing of the 
sort!).

The CRT is interesting, although quite wide, with the electron gun 
assembly mounted alongside the screen and electrodes to deflect the beam 
onto the screen. 

If you want to use one, try to get the entire TV. You need some scan 
correction (Due to the different distance of the 2 edges of the screen 
from the gun, the natural raster is wedge-shaped!). The Microvision TV 
contains a custom chip (22 pins IIRC) that contains this stuff, the scan 
oscillators, the IF strip, and so on. Fortuately, it is possible to feed 
composite video into it somwhow (I forget the exact details, I have some 
notes _somewhere_.

I played around with one of these years ago, gave up when I got fed up 
with the number of poor design decisions in the original....
