I have the same problem as mpspeedy, I can't lift a big tote out of the car. I think I bought the same tote at Joanns that she did, with four extra zippered cases to hold stuff. My rule of thumb is, "if the case is bigger than the thing it holds, I don't use it". So I love my small tote on wheels, just big enough for my machine and light enough to lift out of the car. Then I pack in light totes and use lots of zip close plastic bags to keep things neat.
