Mine is Brent Walters, who for the last four years has had a Sunday morning radio program on a local San Francisco area radio station.
Brent Walters Info
He is the first person I have know about who's approach approximates my own, looking into the original meaning of the text, both in terms of language and translation, and original cultural context.
His presentations are first rate, based in intimate knowledge of the subject as well as clarity of thought.
Samples of his wares can be found at KGO Radio
