If I were you, I would call Chuck from the Bailey company and ask if he has any classroom models in that package. They are used very little and he knocks the price down accordingly. Granted, she has leaders and is willing to help with set up and show you how to use it. If Chuck can come close to her price (and i really do not know if he can) I would call/email her and try to get her set-up cheaper. One thing though, are you sure that 13" will be enough space for you?
