The link below leads to a review of a podcast called Go Magic Go, done by two americans on a weekly basis.

There are many more including one from our very own radio magic (

If you haven't come across these I really recommend that you look into them. They are all free, the best way to get them all is to download itunes and use the podcast function, although it is possible with out itunes.
There are some good points put across, but no secrets. I have really enjoyed listening to them, many a journey has gone quickly thanks to these. I would be interest to know what other people think.
