FINVIZ - Amazing Stock Screener

I am always on the lookout for differentiated (and free) stock screeners that can employ a breadth of fundamental and technical filters to generate a shortlist of stocks to further research upon. I have been using Finviz.com for sometime now and I am extremely happy with the breadth of filters and ease of use. Not only the site provides an easily navigated screener, but also a detailed home page that dynamically updates top gainers/losers every minute. Highly recommended!
