I've personally found Opera's Fastmail & Zoho Mail to be pretty good.

During the start of the whole NSA/Prism spying thing, many people mentioned that those were two they were switching to.

FastMail, while an Australian company, is hosted in the US.

Also, they've recently branched back off from Opera and are now an independent company.
