I have a wheeled case and do not use it. When it is loaded, it is too heavy to get down the steps and out to the car. Then have to lift it into the trunk.
So I have a small folding wheeled handcart that stays in the trunk. I put my machine into a small fabric carring case that is easy to carry, my supplies in another. Easier to carry and when going into guild, I pile them on the handcart with a bungie cord to hold them.
