Sharebuilder's stock grader question.

[jerm1986]

Hey guys, I've just started dabbling in the stock market and was told by a friend to sign up on sharebuilder to get my feet wet. I've been reading a book by Bill O' Neil which is interesting and educational but still a little over my head.
On Sharebuilder they have a stock grader feature which, from the way I understand, adds up all these variables and shoots out whether you should buy, hold or sell. Is it worth it to spend the $12 a month for this feature alone? Is the grader accurate or helpful in any way?
