I use a rolling case bought at JoAnn's on sale. I try to only take my expensive computerized Elna to retreat where it will be sitting for 3 days, otherwise to guild classes, etc I take a much less expensive Brother. I used to take the Elna but was pulling the case along on a snowy day and hit a patch of snow and the handle pulled out of my hand and the case slammed flat on the sidewalk, breaking off a spool holder. much more careful now!
