I was certified by an SSI shop and did not experience any of the problems listed above. My shop had a great reputation and only required students to have mask/snorkel/fins. Everything else was provided in the cost of the course. My LDS in Destin switch from PADI to SSI and when i asked why, they said it was based on the restrictions and flexibility. I am sure there was more to it, but i have now recieved training through both SSI and PADI and my experiences with both left me more comfortable and educated with the sport. Regardless of personal opinions and preferences, both of these companies have survived in this industry by performing and meeting customer demands. There will always be disgruntled people for any service and their opinions are important, however they are not always the end state. It also important to remember that a shop is representing a brand, but they are not the brand.
