Welcome to RBW and awesome news that you're moving to a rebreather.
My advice to you, especially since you are in south east Florida, is to meet some rebreather divers in person and if possible, look at their rigs.
If you want to get on a dive boat with these guys, search for threads on S.C.R.U.B started by ScubaDadMiami. e.g.

I think that is the best way to learn about the sport and separate the FUD from the facts.
