Button hole and zipper foot are a whole different beasts. I have been sewing for 30+ years and those attachments are still on the ignore pile. I do not have a long arm but since you are a quilter I have no doubt that you will be able to master it. Sure, there will be moments of cursing and chocolate binging but in the end it will become as easy as using your DSM. Go try it, ask why they are selling it, ask for servicing records and play with it a little bit. I am hoping to get one next year but with the economy tanking it may just be a pipe dream. Good luck!
