Up here in the Keweenaw only one class is offered publicly, and I heard it was well worth it if you want the knowledge to go elsewhere. I ended up going to the Grand Rapids area for a seminar for HUD and took that time to take a class downstate at Bass Pro Shops and thought the extra money and time to get to the class was great.
I am not familiar with the classes in your county, but do suggest you ask about class sizes, the local one here crams 45-50 people in a class and I cannot see getting your money's worth and the right education out of that type of class.
I had 12 people in my class downstate and we barely fit the information in with quesion/answer sessions as it was.
good luck to you!
