Wuala is a really great client for this, and also comes with other nice-to-haves you may not have considered such as sharing, security and previous version access.

Secure
-Encrypted and your PW never leaves your computer
-Files are in cloud, unless synced, so logout and files are inaccessible
-Files are chunked, meaning the assembled file does not exist anywhere
Many ways to get more storage space (some free)
