I have created quite a few B&W monitors by surgery on an
old TV set. (I have yet to try a color monitor.)
The results were mixed.  Most worked adequately, though
resolution hardly compared to a decent monitor.
They were also troubled by:
    -	Some wavering and wobbling, seemingly tied to 60 Hz.
    -	Serious pulling and tearing at boundaries between
	regular and inverse video lines. (Really anyplace
	that went from mostly black to mostly white for
	a dozen or more lines.

I have had much better experience getting old monitors and
revamping them. There are a surprising number on the market
through surplus houses.  For instance, I just opened a mail-
order surplus catalog with monitors for $23.33, $28.88, $29.88,
$39, and $69.  Many are good Motorola chassis.  The catalog is
from BNF Enterprises in Peabody, MA (617-531-5774).
I've fixed up a couple from this genre, with excellent results.
(Only one of those was from BNF.)

Consider this path the next time you want an inexpensive monitor.
