Database Size Info Without Cursors Or Temp Tables

I have seen a bunch of ways to get the size of all the tables within a database posted on this board. I decided to modify an older one I found here (http://www.sqlteam.com/item.asp?ItemID=282). I set it up so there is no cursors or temp tables. Pretty much just one select statement to return all the info you would need. It seems to be faster than anything I have seen so far. Take it for whats its worth. Thanks to the original creator.
