ByronRace,
I called GP Motor Sports on Camden Ave. They carry the SA approved helmets. He said they start around $130 and go up and up and up. It is the motorcycle shop at the corner of Camden and Union. I was surprised they have them. I don't like to buy stuff off the internet, since you can't try them on. It took me about an 2 hour's trying 30 different helmets before I could decide on my motocross helmet.
