You should be a little more specific and describe your needs/wants/budget. I am partial to the Atomic Aquatics Cobalt, for its large bright display, super-ease of use, and its long life rechargeable battery. However if you plan to move onto Tech diving, Trimix, and multiple gases/deco, then a Shearwater or something along those lines is probably in order. I had been considering a SUUNTO D9, until I went and looked at one, and realized that I could not read it (over 40 eyes) - Then I thought "Ill get one of those fancy tech diving computers with the OLED display and just not use the Trimix settings- Until I realized that at least at that time, they needed to be recharged every 72 hours or so, and I could definitely see me missing dives due to dead batteries. I think if you could tell us how much you can spend, and what you need it to do short and long term, we can help recommend the best computer for you. While the Cobalt fits my needs, and force-sit into my budget, it might be entirely wrong for you. Most of my friends laugh at it, but they are all advanced-deco tech divers. For a new Nitrox rec diver, it is perfect because it is mindlessly simple to operate. The last time I played with a regular dive computer, I felt a bit like I was programming a VCR, and I really think that in this day user interfaces should be simple.
