I strongly second that. I have been doing this for a long time, and in 2004 I spent 2 weeks in Richmond, VA at Arbormaster training. Yes, It cost me a bunch of money (training expense, hotel & food plus 2 weeks of lost work) however, it was probably the best money I have ever spent on my company. Since the training, we work MUCH safer, and much more productively. I went back last fall and took the only remaining course (Precision Felling 2). I can't say enough about the quality of the instructors, the amount of knowledge and skill that was learned and the overall positive influence on my business. Do what you can to take as many Arbormaster courses as possible.
