TEFL

I am seriously exploring the possibility of obtaining a TEFL
certificate either through a distance learning program or in a
classroom setting. I have an undegraduate degree but it is not related
to linguistics. Could anybody who has taken either route shed some
light on this subject? I have visited several websites including that
of the credentialing body for distance learning, but I would prefer to
advoid all of the hype and actually hear from somebody who has
graduated from either one of these programs.

Thank you.
