I like a lot of Clinton Anderson's techniques. Probably the best way to learn more without dropping a lot of money is to find a copy of his book.
The book is set up really nicely with lots of detail in both the general theory of horsemanship as well as how to execute and troubleshoot his exercises. I don't know if you would find it in a library in the UK, but ordering a copy online is well worth the $17.99 American for a used one.
It's a shame there's no RFDTV in the UK (to my knowledge, anyway). CA has a 1 hour weekly tv show on that station that tends to be helpful. Recently I think it's been swamped in marketing hype like the rest of "Mainstream NH" :roll:, but his earlier episodes were packed with helpful and useful info.
