I've enjoyed Jeff Walker's writing style and found his information to be useful. Jeff Walker is the author of the Walker Market Letter. His teachings include; day trading, low risk investments, and pretty much anything to do with finances.

Jeff Walker's publication of The Walker Market Letter is very informative and covers the basics just enough to get you excited and motivated. His goal appears to then get you interested enough that you'll want to get involved with his Walker Market Edge, which is a paid version that has a lot more advanced information.

Jeff Walker is supposedly the man behind the marketing strategies used in John Reese's Traffic Secrets, Frank Kern and Ed Dale's Underachiever Mastery, Jason Potash's Article Announcer, and Yanik Silver's Underground Online Seminar.

I do recommend Jeff Walker.
