I suggest if you have a friend who sews or quilts ask for their opinion. then find a dealer who sells machines and is willing to let you try them out and help you decide . Tell them the price range you are willing to pay.
I have three Janome machines. Not one of them has ever had to go to the shop for a repair. Bought my first one ten yrs ago. They are workhorses. And good luck in your search. Marge
