If you want to be a therapist, NLP Comprehensive is a good choice. I'm sure there are many others for this, but none that I have much information on.
For practical, real-world training Ross Jeffries is good and so are Tom Vizzini and Kim McFarland (www.essential-skills.com). Kenrick Cleveland is another good trainer and his Maxpersuasion 2000 home study course is great.
