Thanks everyone for your input on the different qualities of the dive computers. I still have not made up my mind yet as to which one would be best for me. I've stopped at a couple dive shops to see if they carry the Cressi Archimede II and neither of the shops I went to carry Cressi products. One shop told me they didn't like the quality of Cressi products and woudn't recommend their dive watches. I've been told and have read a lot of really good reviews about Suunto (apperantly all they make are watches, computers, monitors), so I can appreciate that they would be made of good quality. I think my best bet now is to get my hands on one, play with it and maybe try one out in the pool.
Just because that is all that they do doesn't mean they are great at it... A couple co-workers have had some fatal issues with their Suunto's, no different than any other dive computer...
Careful note about the Suunto's - they are very conservative - one of those co-workers borrowed my Oceanic today and at 40' at the end of the dive, the Oceanic gave 40 minutes of NDL, the Suunto (her spare) gave her 27 minutes... Conservative isn't necessarily a bad thing, however there haven't been any reports (to my knowledge) of divers using the Oceanics getting bent any more often than the Suunto...
