I have the 720 and love it. On the advice of the salesperson, I kept the Styrofoam packaging because I especially wanted this machine for airline travel. I decided it was more important that the front face of the machine was protected so I cut channels for the luggage pull up handle into that piece of Styrofoam and then placed it within a large plastic bag (so it would not 'shed' all over everything else). It fits perfectly into a regulation airline carry-on and has had its share of adventures traveling to and from retreats. Definitely a keeper in my books.
