I don't agree with Garrobo. I have yet to do my AOW, but will be doing it in the Keys this December off Looe Key/Big Pine Key. Having logged a year of diving, I'm at the point where I've gotten more confident and skilled, but think that spending some money to work with an instructor at this point to really fine-tune my bouyancy, gain confidence doing another night dive, work on navigation, and do a dive that is a little deeper than I've been while getting to see a cool wreck (Adolphus Busch Sr. at ~100') seems worth it.
As for the price, the shop I'll be diving with does only 6-pack service and charges $77 for a 2-tank trip (assuming no gear rental). Since I'd be doing at least 3 trips anyway, I'd be paying $231 for the diving. The AOW includes the instruction and the 3 dive trips for $390. So, the difference is only $159. I'll admit that I haven't been on a boat yet that has strickly limited depth, but the AOW will ensure that I can make the dives I want if I ever do.
I see that you are a newer diver, so I imagine you are in a similar situation where you'd like to continue with your training and it looks like you've already made the decision to do it, so that's not the main point of your post anyway.
As for recommendations, I have yet to dive my AOW, so I don't know yet how it will go, but they (Innerspace Dive Shop) was well reviewed in a few places I looked. They're a little outside of Key West on Big Pine Key, so that may not work for you. My SO and I wanted to dive Looe Key because it is our favorite spot in the Keys, which was a large part of the decision to do our AOW there. They do have both Padi and Naui. Just another option in case you're interested. Good luck!
