I took one last year but I had to fly to another island (Oahu) to do it.
It was a great experience and I still can't believe I drove 26 miles in a very small parking lot!
There's no MSF course at all offered on any of the neighbor Hawaiian Islands (Kauai, Maui, Molokai, and Hawaii), which is really scary when you think that's over 250,000 people, about 25% of our state, that can't take the course without having to spend an additional $300-500 (~ $500-$800 total) to fly over, stay 2 days etc. Which almost no one does. According to my MSF instructor, I was the first person from Kauai he's seen in over 4 years.
