US companies, market caps, stock price

I am looking for a tool that gives me a list of all US companies together with their market capitalization and current stock price level. Ideally something that is continually updated. I would like a list that I can download into xls so that I can look up the data against companies that I have selected for checking for set-up potential.

Secondly, does the Trade Station platform offer such functionality? I have not signed up to Trade Station yet.

bingo!

This here is exactly what I am looking for - however this covers only the top 500 - I guess I am after the top 2000.

also found that, which has information on ALL US companies, but it was only up to date as at January 2011.
