mack diver---I checked around. Some had it posted on their website, some have call for more info. I can't find my notes this second, but when I do I will edit this message. Deep blue's phone number is disconnected, so I scratched them off. Toms dive was more. Yours was the same. (your shop is nice, just farther south than I want to drive) Dive world quoted me 165 then came down to 150 when I said I was calling around. One shop named the advanced specialties. I did not even think to ask what Royal Scuba's specialties where. I will have to remember to ask. I have talked at length to both of the instructors and they seem like geniune good guys who want to bring more people into the enjoyment of scuba but with safety in mind. They talk a good game and are very confident in their abilities to properly train. I am still hoping to get some feedback from their former students. I have also heard that Randy Beckmann is one of the best in the Austin area, who used to work at Austin Aqua Sports that shut down, but he is retired now so he might not be a viable alternative either, not really sure yet.
