I have several wheeled cases -- use them to transport several machines when I teach folks who can't afford their own machines. My favorite for my Janome 6500 was from Joann's. It's the largest machine I have and had trouble finding one to fit -- it just fits. I have another from Nancy's Notions, but must say it isn't as sturdy, looks nice, but doesn't have the exterior supports. Also have several cases that you just pick up and carry. Believe me, those on wheels are wonderful! They still require you to lift the machine/case up to the table and down again. I also lift them when I go down stairs so I don't jar the electronic machines. Wouldn't it be nice if we had some anti-gravity machines so there would be no lifting whatsoeve?. Perhaps in 2020???
