Online repositories

Whenever I need to send large files to people or groups of people I use http://www.yousendit.com/. It is simple, intuitive, and works well. The only caveat is that files are only available to download from their servers for 1 week.
Now, thanks to the cool people at http://www.workhappy.net/, I have been given choice:

• http://www.dropload.com/

• http://www.dropsend.com/


• http://www.box.net/ (Thanks to Scobleizer)
  

I will soon be checking which one is better.

[Update]: http://www.dropload.com/ has a 100MB size limit and 7 days time limit. Guess I won't be using this one fo'sho.
[Update 2]: http://www.dropsend.com/ will definitely have a closer look, since their founder's blog is one of my top reads.
