I found a new page at Microsoft this morning. It might not be new, but it is new to me.
On the linked page, click the Download & Trials link to the right. It appears to be a good place to start most any download search. Not only are all the download categories available from one easy-to-use page, the All Microsoft Sites links to the right make the page much more versatile than their previous setup. In the past, I've spent too much time clicking backward or forward to find a link that was available just a page to two away.
This isn't really an Office tip, but I like the new setup so much, I wanted to share it and say thanks to Microsoft. I apologize in advance if the look isn't really new. I can't remember the last time I tried to download something from a generic page like this, so it could've been a while.
