Any TM practitioners here?

[Comicstripper]

I've done a good deal of research on Transcendental Meditation--is anyone here a current-or former- practitioner? I understand the basics of the technique but could use some clarification.
Also, I understand there is some controversy surrounding the validity of some of the experiments conducted, and whether or not the program is worth the excessive amount of money they charge for instruction...which is why I'm coming to you all.
Anyone? How's it done? Is it worth it?
Thanks.
