I am a firm believer in training with everyone you possibly can. Even a bad experience could be good if you learn that this is not what you want to do. However, look carefully at who you want to train with. Ask around, and have a good idea of what you are getting into. Understand the cost benefit analysis. Is the training reasonably priced, will I gain from it? Is the material to basic or too advanced? What is the instructors reputation? Etc… Think through your training and be discerning…
