I guess I am old-fashioned. I bought a cargo dolly (aka hand truck) that has rubber wheels. I strap my machine to the bottom (in it's plastic case), then add a tote bag with all my other quilting needs on top of the machine. Both are secured to the dolly with a heavy duty bungee cord. It's very easy to maneuver and I've never had problems going to/from class with it. I bought mine at either Lowe's or Home Depot for under $50. I've looked at the machine totes and can't justify the cost. Maybe I'm cheap? Then again, I don't own a very expensive machine - mine were under $300 each. Just my thoughts....
