we have an 8th grade quilt class and most of the machines we use are the older, tough models. The newer models with all that plastic just don't hold up with these kids. Its my job to keep them oiled cleaned and in running condition LOL sometimes a real test. I have a kenmore from 1978 that had developed a click click evertime the needle went up and down and my local guy fixed it...said there was just a glitch in the timing and everything OK now. Love it for jeans etc.
