Agree with a lot of the stuff above.
Depends on the diving you are doing - in many locations a computer is not actually necessary but I think it's important in this day and age that people should use one, and should know how it works! like all gear, they don't come cheap, although the out-of-production Suunto Gekko can still be found new and unused online for around $100 in stock clearance sales - they are great, basic computers. If you're diving one or two times a year, then renting gear is more cost-effective, because it might cost you $50 to rent a computer at $10 per day if you're only going to make a short dive vacation once per year. If you get addicted to the underwater world, then it makes good sense both practically and financially to buy one.
