The three that I am interested in are XS Scuba seaair tri-metal, tusa rs-460, and the oceanic alpha 8/sport. All of these are very favorable on scubalabs. I know that the oceanic is completely unbalanced, the tusa is only balanced on the 1st stage, and the tri-metal is completely balanced. Price is not an issue. Maybe you could mention what you DON'T like about any of these regs, or problems that you have had with any of these regs. I will be buying tomorrow. Thanks!
