Thanks for your input, folks. I agree this is not a machine intended to be carted from class to class. However, the shop where I bought it included 10 lessons designed to get new owners completely acquainted with all the machine can do. Thus, I have to take it to those classes. Thought if I could find a nice sturdy cart, I could also use it to transport my baby back and forth from NC to FL - can't imagine leaving it either place as we are half the year here and half there. I will look a little more closely at the softsided carriers.
