i have a singer quantum 9940. pretty cool machine with lots of stitch functions and a variety of feet. i just ordered the invisible zipper and pintuck feet. i think i have one more to buy to complete my feet collection. i have extra button and buttonhole feet due to miscommunication between the dealer and i. i can keep them or sell them. i have no idea yet. all in all, it's been fun getting to know this machine and i'll be posting more about what i'm working on soon.
