Vyper, NiTek Duo, Atmos 2, etc.

[taliesin58]

I currently have Atmos 2, but i have a friend who wants to but the console from me. I want a wrist mount anyway, and am seeing if I should upgrade to a Vyper or NiTek Duo. I was also looking at the Mares M2.
Please let me know about what you think of the various computers, good or bad. Thanks.

I had a Vyper for a while and really liked it. I sold it and got a Cochran Commander Nitrox. The Commander has a bigger display and the ability to switch gasses. I have a buddy selling a Vyper with 2 dives on it if you are interested, pm me.
