Demagnetizing on a *cassette* four track is not necessary. Due to the
slim width of the tape and the relatively slow speed of the transport
(even when you're using double speed), magnetism does not really
accumulate. On top of that, every time you put the machine in record,
it demagnetizes the heads so even if you are concerned about it, the
machine does it for you.
With reel to reel tape decks (stereo or multi-tracks), demagnetization
is very important, as the accumulation is too much to be eliminated by
simply engaging record.

I use a degausser myself, did cost me about US$20 but there are some
that cost US$60. I don't know if they are better. Mine's very useful
for any kind of tape machine. I prefer it over a battery-powered tape
unit; those are only good if you can't use a degausser, e.g. in a car
radio.
Degaussing should be performed about every twenty hours of usage.
I use a degausser with my home cassette deck, a Nakamichi. There were
some people who asked me if they should go and buy such a device and I
gave them mine so they could test. They have never done so in about 2
years and after degaussing they have lots of treble which they weren't
