Welcome to our passion! I would recommend if you are just getting started, use the rental gear from your LDS (if it's a decent shop) until you really decide you want to dive. That way if you try it and decide you don't really like it, or perhaps discover some kind of medical issue that will keep you from being able to dive, you aren't stuck trying to sell a lot of gear that you will never make your money back on. Most places will require you to have a mask and snorkel, but will rent you the rest. Just my 2 cents.
