AGottZ,
I've had the Suunto Cobra for 5 years now and love it. It's easy to use, especially when you're switching from air to nitrox and back. It has big clear numbers and icons. It also keeps track of your breathing rate and counts down your air time at whatever depth you're at. On your way up to your safety stop, it keeps track of your ascent rate with a meter and you can really tell if you're ascending too fast. The Cobra has a number of alarms that tell you if you're running low on air, ascending too fast or missing your safety stop--these all can be turned off of course. I seldom hear the alarms since I'm usually diving with a 12mm hood and my drysuit--in warmer waters, the alarms tend to be annoying, since they're so much louder, without the hood. The Cobra can be adjusted as to how conservative (or aggressive) you want to dive. I usually have mine set in the middle. Also, if you plan to do any altitude diving the computer can be adjusted accordingly. And the best part of the computer is the ability to download it to your PC. Since buying the PC download kit, I seldom write into my logbook. I do it all on my PC "logbook" where I can print out the charts, divelogs, and set up any parameters for the printouts.
Have any other particular questions? I'd like to help.
