I use Acronis having moved from Partition Magic. Whichever product you go with, test the rescue media before you need to use it in anger. I have a rescue USB thumbdrive glued to the case which I know will boot the system and locate the backup media, wherever I am.
For imaging, you might check out Easeus which is a Partition Magic clone, and free for home use.
Comodo Backup is a free backup program which has some nice features, including real-time backup, but like other Comodo stuff it's not as polished as the company thinks it is.
