- Oh, how I wish I could afford this. Dr. Chapell is an excellent teacher. I have thoroughly enjoyed the little snippets that I've seen of his teaching. I'm sure this course is well worth the price and I would strongly encourage those who can afford it, to purchase it. As for me, I will make due for now with reading his excellent books on preaching. I have given this course 5 stars based on what I've seen of his teaching previously and his books.
