Well, there is really only one computer that impresses me and that's the Liquivision X1
Liquivision
I don't have one but is I were even thinking about deco or voodoo gas diving, this is the one I would buy.
Meanwhile, back in the land of reality, I have a Dive Rite Nitek Duo for nitrox diving. It is a great computer and the new software is far better than the original. The new downloader USB driver is vastly improved.
I think of the Suunto Vyper as an adequate 'recreational' computer - like my Nitek. The difference is that I probably can't read the smaller display of the Vyper. At my age, I need large and bright displays. Even the Nitek isn't as bright as I would like.
That's why I want the X1. It is VERY BRIGHT!

I was going to say Liquivision also, but that is when I get some money. I currently dive a Suunto Vyper (first generation) for recreational, and I am looking at a UWatec Luna, or Diverite NiTek Trio.
For tech, I use my Vyper in gauge mode, backup UWatec bottom timer, and GAP Software.
