Just thought I'd mention a good experience with "World Watersports" in Key Largo
(affiliated with Diver's Direct). I was surprised to see that they beat all Diver's Direct catalog prices, and in the course of outfitting a scuba
package I saved over $200 (not to mention normal shipping
charges). Staff there was helpful, even to the point of delivering the stuff to my dingy, a few miles away.
If you're in the area and need equipment
in Rock Harbor and pay'm a visit.
