I bought mine from overstock.com. I measured my machine first , and found that many of the bags advertsied online and at Joann's were just an inch or so too small. The bag I bought has a plastic handle to pull while rolling, but also has two web handles that meet at the top of the bag for easier carrying up and down steps etc. The plastic handle is a bit flimsy but works fine. The bag also has padding inside and an added pad for extra protection. The added pad is not attached so you can slide it in between the machine and the bag wall. All in all, i am happy with it.
