Hi Drew, I have used simplywallst's free sign-up for a year or so, and have just paid for full access. I have found it useful for telling me how much debt the company has, whether insiders have been buying (or selling) recently, whether it has a rosy future and whether it is over-or-undervalued. I also look at Shareclarity and Yahoo for advice. Often they disagree with each other!
