hello to all. just a normal guy, loves the water, I don't own a rebreather, and the more research I do, the less sure I am of where to put my money, and for all intents and purposes my soul. I want something that lets me go deep, long, repetetively, safely, and economically. Does such a miracle actually exist ? If so, please help me find it. The more I learn, the less I

know...
