I also have been very pleased with CloneZilla, although it's really
more intended for mass / repeated deployments, so sounds like overkill
for your current task.

My recommendation for this time would be just to use partimage
directly.  Clonezilla actually uses partimage "under the hood", along
with its various other tasks, so you get the same benefits of usual
usage types of both, just simplified.

Now if you ever find yourself trying to image a room of 40 identical
computers or whatever, then Clonzilla is the ticket, hands-down.
