any good tv shop should have one, but most won't touch anything for less
than $70, although some are still nice.  if you can do a little
electronics work it's easy to make a very good degaussing coil easily. 
you take the coil out of a dead old color tv (watch the allies by
dumpsters!), it's usually wrapped with electrical tape and has 2 black
or white wires coming off of it.  what you do is carefully twist it into
a figure 8, fold it over where it crosses itself so you have a smaller,
thicker coil.  make a figure 8 again and fold it over.  you now have a
coil about 6" in diameter with the windings very concentrated.  you hook
this up to an ac wall wart/transformer with some speaker wire or zip
cord.  12-18 volts is about right for the coil, i've got one on an 18 v
transformer and it works great, draws about one amp and doesn't get
warm.  

you want to turn it on away from the monitor, move it close to the
monitor, make small circular motions and move it around the screen,
gradually make bigger circles and then slowly move it back away from the
monitor.  once it's at least 5' away you can turn it off and check the
monitor, when it's bad it may take more than one pass, you can
concentrate on the bad spots, just pretend you're buffing off rough
spots with a circular motion.  always move reasonably slowly (not quick
or jerky, but not at a snails pace either) and always turn the coil on
and off with it away from the monitor or you can magnetize it worse. 
i've done this with some old sun monitors in big steel cases that were
incredibly bad, it took 3 long thorough tries but they eventually came
back to normal.  so go scrounge a degaussing coil from a 21" or larger
tv, a 12-18 v 1 amp transformer and your set.  the really nice thing is
that unlike most commercial degaussing coils it won't over heat so you
can take your time.  you should avoid getting close to the neck in the
back of the picture tube, there are magnets there that help the
convergence and you don't want to demagnetize those magnets even
partially or at best you'd have to readjust them.  just work around the
face of the tube and the front corners of the case.
