Website that will give financial information for companies in different years?

Looking at 10-K reports for different periods easily enough gives variables like book value and book value of market capitalization, but is there a website that you use that would give variables such as EPS, EBITDA, EBITDA margin, etc?

I have found/used advfn but the numbers do not match up with the most recent 10-K reports for the companies. For example, advfn states that the most recent revenue for Abraxis Bioscience (acquired in 2010) was $447mm while the last 10-k report from 2009 states the revenue as $359mm.

Is advfn using more accurate/recent data than the 10-K report for the FY ending Dec 2009? Is there a better website to get these values?

Thank you for any help or guidance.
