Cody Moya is a name that most internet marketers recognize. He has produced a TON of products, and most of them have been good. (Personally, I'd stay away from any of his co-op list building options.)
I just received an email from Cody announcing a new membership site that he's created that offers 120 HOURS of MP3s, where many of the top name internet marketers have discussed various ways of making money online. Audio is a hot topic lately, and hearing these guys talk about what works and what doesn't really helps you to understand the industry.
