I agree with the others, 2-3 weeks should be all that is necessary. Is the machine useable? Could you use it until the part comes in? If not, I would definitely ask for a loaner. You should look for a 2nd machine as a backup. Featherweights are great and they don't take up much space. I use mine more than my Sapphire for general sewing. I haul the Sapphire out when I want to use decorative stitches or to quilt.
