My favorite research link in StockCentral is to MSN Money:  Stock Scouter. 

I was disappointed to discover recently that Microsoft dropped the Scouter from their recent redo of the MSN site, which I learned from the Microsoft Community forum.  Also, from the forum, I learned that Verus Analytics, the source of this data to MSN, temporarily is providing an Excel worksheet with this data twice a month for free by email while they seek a new partner for this data.  You, too, may request a copy in the meantime at:

customersupport@verusanalytics.com

I just received my first copy and am happy for the data provided, which is for personal use only and may not be shared. There is no charge for this data.
