I have the old DHE cassettes and the more recent one on CD.
I went to one seminar with him during the whole DHE thing. It's pretty much just Bandler.
I knew a lady who was taking seminars with the old crew, and she said that DHE was just a lark. It's was just Bandler and she really didn't see anything new about it.
So, yeah, I have tried it. I think there is a lot of cool stuff to pick up from Bandler. A lot of it is unconscious skill.
I was asking that lady I just mentioned about inducing states and if you had to bring someone back, perfectly, into a past experience with a state in order to induce it fully. She said yes. I smiled and said I didn't think so. She replied, "Alright then, smarty pants, how?"
And then I told her about this time these teenagers were asking me to buy alcohol for them. I told them they could get drunk without alcohol. They said, "Nuh-uh." I said, "Yeah huh," and asked if any of them would dare to be hypnotized. One guy said, sure.
So I hypnotized him and made him drunk. It'd be too long to go into the particulars here, but I basically used anchoring, suggestion, and stacked states to create a really, really powerful state of drunkenness in him. I mean, he had flushed skin, sweating, blurry, red eyes ... the whole deal. After a minute or two of being on the ground and unable to get up he yelled, "Get me out ... make it stop!" So I did.
He was totally sober again in less than a minute.
She looked at me, surprized, after telling my story and said, "You learned more from Bandler than you think." Thing is, I think my recounting of the story was even affecting her. It was a great compliment. 
I knew, deep down, that I was using voice inflection and language patterns I'd picked up from the good old Dr. Bandler himself.
