HammerheadGuy,
If you want to see a beautiful dive shop, the Jack's is the place. I loved going in there. I have two kids and would you believe it, they have kids stuff in there as well! It was a nice surprise from other dive shops I've been to.
Great group of friendly guides/instructors/boat captains. Unfortunately, I think the prices reflect on how much rent they are paying. I did three night manta dives with three different outfits when I was there and I paid at least $25.00 more. Same dive as the other boats.
I had great service with the other dive ops and paid less. Thumbs up to Wanna Dive for a small group and friendly boat. To be honest, every dive I went on served the "same" sandwiches. Nothing different there.
I only wish I had tried Big Island Divers. Never got to check them out.
Have fun!
Chris
