I have a large rolling tote I got when I bought my first embroidery machine. The machine is so wide front to back that it won't fit in a regular tote it has to have a huge one. For my serger I found a Thermos rolling cooler at a thrift store that's the perfect size, and being it's a soft sided cooler it's well padded. 6 dollars versus 100 dollars? Oh Yeah.
