Ask HN: Best virtual mailbox service?

Going to be moving soon, looking for a good mailbox service, like Earth Class Mail (http://www.earthclassmail.com/) or Virtual Post Mail (http://www.virtualpostmail.com/). Both of these look OK but I was curious if anyone had a better option. Simply looking for a service where I get an address that I can give to everyone and the company will scan and upload my mail for me.
