Anymore most of the computers have very similar features. I would look at all the computers available to you in your area through your local shops and decide based on features and the money you want to spend. I prefer hose mounted non-air integrated computers for the following reasons:
Wrist mounted computers are easier to loose or break.
Air integrated means you have no idea how much air you have when the battery fails (and it will without warning sometimes).
Nitrox capabilitie is nice to have even if you don't plan to dive with Nitrox right away.
I like Aeris, Suunto and Oceanic comptuers. I would look for one that has easy to use buttons (I dive cold water and wear 5mm gloves and some buttons are a pain). Make sure it has a backlight feature for low vis and night diving. Other than that, without getting into a lot of technical discussion about algorithms and such most major brands are pretty feature rich.
