There’s a nice front end GUI for ImageX.exe (the file-based imaging tool Microsoft uses to install Vista, but can be used to make images of any NTFS system). It’s available at:

Of course, you need the WAIK (Windows Automated Install Kit) to use it. Too bad that’s 1 GB in size. The latest version (1.1) is available at microsoft.com downloads.
