Thanks for all the great responses. I have a rolling tool chest, the Stanley 3 in 1 that I always used for my featherweight. I was really amazed at how much quicker I get things done with my new machine having the automatic cutter, needle threader, knee bar etc. I hate the thought of not having it on my next retreat but it won't fit in the Stanley. I have looked for luggage or tool chests (since anything marketed for quilting is so much more expensive than things made for tools) and not found anything that would fit or seem to work for my needs. The rolling duffel bags were a possibility and seemed to be the right size but I was worried that with no frame the machine would be at risk for being damaged.
