Finding a good instructor (great even) is far more valuable
it all boils down to the instructor.
Instructors are no doubt important, however, the program that a certain dive shop runs will most likely tell you more. If you have a shop that has a solid training program in place, a good reputation, proven track record and solid principles with regard to teaching, then you will most likely find good instructors. In other words, if the particular person who manages/owns the dive shop is steadfast in training students the way they should be trained, then that manager/owner is probably not going to settle for half-assed instructors. You can learn alot by visiting dive shops in your area and asking questions about their courses...their philosophy regarding training...how long they have been in business...how long the particular certification takes to accomplish and what they expect of students. Pay attention to how they answer your questions. Pay attention to how interested the shop is in answering your questions, etc...
