I agree completely.
I'm perhaps the forum's biggest "Al Brooks enthusiast" and even I'll admit that his books are badly written and very badly edited. Their content, however, is great. I probably learned more things that eventually translated into earning a living from his books than from anywhere else. But by no means are they "easy reading", to put it mildly!
For anyone interested, however, his video course (about 35 hours of high-quality tuition spread across about 55 videos, as I remember) is in a different league altogether: far easier to understand, and I'm sure that for most people it will be far more helpful than ploughing through the textbooks (and "ploughing through" is exactly the right expression, from my experience!). The video course is more expensive than the books, but in my opinion $250 for 35 hours of tuition, in that league, is really a steal.
He's definitely "one of the good guys".
