I bought the Tutto large trolley when I bought my Janome MC6600P just for the reason to take it to and from classes to learn how to use the machine. It didn't come with a hard cover. I use it when I transport my Viking Designer Topaz too. It doesn't have room for the embroidery arm, but that is fine. My Viking has a handle on the top, so quite often I lift the machine and wrap my arms around it and just carry it. I strap it in the car with a seat belt, which I believe holds it better than if it sits in the case.
