Toodie11, I agree 100% with the 7700's issue with changing the feet, I with the Acufeed feet were easier to change, but they aren't, oh well. I loved my 7700 and I still have it, but recently traded in my 11000SE for the 15000 so the 7700 is now my second machine with the 15000 being the new baby. The 7700 is a work horse and I have had no issues with her.
