I don't know if you are looking for answers to what you should buy? My main and only machine is a Bernina 930. For lasting they can't be beat. But I also have two old old old Singers. One just old the other a FW. I wouldn't own a new Singer but these old ones are like the Bernina's they never give up no matter what I throw at them. I love my machines and would like to get either a crank or a treadle Singer and I wouldl be a happy camper until some other love came along lol.
