I have a friend that worked for him some years back. She has fond memories of him as a person.
I have listened to some of his teachings, I especially like the one on the judiciousness of God.
I have not listened to the series on dreams and interpretations yet, but should get to it one of these days. (My friend will let me borrow it.)
I have heard of some inconsistencies/negativity in the past regarding his ministry, oh some 10 - 15 years ago. As of recent, I haven't seen anything necessarily off-base in any of the materials I've reviewed. Sometimes the workings of God in a person, help to better center them over a period of time. Perhaps that's the case here.
I'm glad your enjoying the fruit of his ministry.
Keeping my eyes on Jesus! Blessings...
