went thru padi about 4 years ago. It was 175 for basic open water diver course. Plus I had to buy books (around 60 bucks), my own snorkel, fins, mask, and pay another 150 for a dive weekend in Gloucester, MA to get certified. If you can swim you can pass this class and scuba diving is wicked awesome!
Only bad thing, I spend around 3k for my gear but I had to get top of the line everything and a dry suit. You can get a nice setup for around 1k including everything you'll need.
