I strongly recommend that readers follow some of those links. One of them will lead you to the "Wizards of Money" but you'll only find 13 of the 22 episodes (First 15 are listed, 11 and 12 are missing). Also the wizardsofmoney.org and .net sites seem to have evaporated. However, seems to be working for the time being and lists 22 episodes. I'm downloading the missing 11 and 12 as we speak. My wife and I have just listened to the first 3 and its brilliant stuff. Not quite as comprehensive as Quigley, but a lot more up to date and much more detailed about nitty gritty usury - like "predatory lending".
