What kind of dives do you normally make?? Are you wanting to get Nitrox certified?? Just a few questions. I bought a computer about 6 months ago when I first starting diving, now I just bought the Atmos Elite--this is a great computer. The reason I bought the Atmos is because I wanted to get Nitrox certified, if anytime in the future you plan on getting Nitrix certified buy the computer now, you can use it will air, but it will be ready when you are ready. I have not used any of the computers you mentioned above, but the Atmos is great and about the same price without the transmitter, which you could get later if you wanted too.
