I enjoy listening to the podcasts by Dhammaloka Buddhist Centre (operated by the Buddhist Society of Western Australia). The podcasts are available for free from their website and on i-tunes. There are two sets: Dhamma talks and Sutta talks.
I really like the style of their teaching Venerable, Ajahn Brahm. He is humorous and although he himself is a Theravadin monk he is very much non-sectarian and often talks how he enjoys being in the company of practitioners from different traditions.
Apart from being quite often funny, the Venerable’s talks are also full of practical down to earth advice and beautiful insights into Buddha‘s Dhamma.
