I have a Lily 540 Husqvarna that really only gets used once or twice a year at retreats. Touch wood.... I have never had a problem with it, although it does sit in a temperature controlled room day in and day out. As soon as it is plugged in.... it does it's little realignment as computerized machines do... and off it goes, ready to use. Do you have a machine that you are thinking of leaving there or would this be a new purchase?
