This should be a one star post -

Favstocks.com has had typically very inaccurate information. The admin of that site has spent a huge amount of time spamming on the yahoo boards and his method of letting people access, and ADD Data, after just two posts is a recipe for disaster. He is trying to profit from information provided more accurately on other sites through ads.

Again, there are much much better sites out there with better research and data. While some of these charge a fee, the fees associated with it can be written off and are minimal at best. Personally, I pay the fee to get better information and take the write off on my taxes.
