One thing to consider though is if you went to a hypnotherapist no matter how good they are you would only get their one style. ( though i am being a bit contradicting here,as a good hypnotherapist should have more than one style )
Experimenting with many MP3's first, can give you a wide range of hypnotists styles.From this you can find which style suits you the most. You can find some surprising,and some just dont work.
I make my own MP3's for myself to listen to.I have listened to many tists including a few on here and have taken all the parts which i have found work with me. A few which i didnt think would work,but was surprised at how well they worked. And when putting my wife under i use a totally different style than with myself.
The last point i shall make is that the points made on the FAQ's are just one persons view.
My advice is to try what you want to and make your own mind up. I am always experimenting with hypnosis - usually on myself,and it hasnt effected me yet blurbuldsklkudgfnlun arrrrggghhhh wibble,oh no the aliens are after me!
