You can't go wrong with Charles Stanley.
He is a mild mannered man who clearly love the Lord and has preached faithfully for many years.
He doesn't often get into the meatier doctrinal issues, but what he does preach on he generally does a very good job with.
There are a few beliefs that he holds that I do not believe are Biblical, but as they are 'orthodox' views, I do not necessarily hold that against him.
If I bump into him on the TV, I will often stick around and listen.
