I listened to Bob Brinker's Money Talk before he retired about a year ago. I used to listen to Dave Ramsey before I just couldn't take his sanctimonious whining anymore. His basic advice on debt reduction and avoidance is something that all people should follow. But in other areas, specifically investments, you should look elsewhere, IMO.
Now I primarily just listen to Option Alpha, Chat with Traders and a couple of F1 podcasts. I agree... listening to good podcasts is a great way to pass the time while driving.
