I also like Buck a lot. I like his mentor Ray Hunt even more. If you really like the NH type trainer, you might check out Stacy Westfall. I've seen her work horses in person and have watched some of her dvd's and she's clear & concise in her work.
Regardless of what method you use, it's all about what works for you & the horse you're working with. One of my students is obsessed with learning and rents dvd's from giddupflix, she gets 2 a month for like 15 bucks or something ridiculous. You could check out a ton of trainers over the course of a year and not have spent what you would on one trainer's dvd collection.
Fyi, there's no law that says you can't hug, love & smooch your horses :)
Life is like a camera. Focus on what's important, Capture the good times, Develop from the negatives and if things don't work out, Take another shot.
