i have the attachment kit- have had it for a couple years now- i love it - it works very well- has a variety of attachments all just the right size for my machines & computer-i purchased my kit from Nancy's Notions- it was under $20- and since it costs me $70 to have my machine cleaned at the dealer's i figure it more than paid for itself the day it arrived. i think Clotildes also carry them- and Keepsake Quilting. there are probably other places- i just haven't paid attention since i have one-
