Hi Raphyy,
Welcome to Scuba Board. I believe you made a very wise decision. While a PS3 can indeed be a lot of fun, it is obsolete before you buy it. The next version is already being planned before yours hits the store.
Diving however is never obsolete. I've been doing it for over 40 years, and I'm still having new adventures. Plus it will get you outside and active, which is something everyone needs to do more of.
Let us know how you make out with your course and if you can send us some pics. Trust me, the first time you see your 1st large palegic, whether it's a shark, dolphin, turtle or whatever - it'll be much more of a thrill than Grand Theft Auto could ever hope to be. Besides, once you start diving, many of your friends will become curious and maybe want to try it too. You could be the head of your neighborhood dive club.
Stay in touch!
George
