Pat or Clint? Hmmm...I'll take the local trainer who worked with my horses. Why? Because Clint & Pat aren't likely to come to my house 4 times/week and train my horses at a pice I can afford, and I need someone who is better at horses than I am who will do the work I can't do - read my horses and teach them one on one.
I don't really mind them selling DVDs, although they both get a bit heavy handed on their marketing. But I wish the average owner who needs help with a horse would think, "Is there someone I can hire?" Because if your knowledge of horses has resulted in your horse having a problem (and I speak from personal example), then a DVD won't help.
DVDs are for those ready to start training, but are often bought by folks who aren't ready to ride, let alone train. Some fault belongs with the marketing, but a lot belongs to people who want a quick or cheap fix to a problem that, in reality, they are responsible for creating. Again, I write as someone who has been guilty, although it isn't fun admitting it.
