The new Singers aren't up to par, in my experience. I sold them for 1 1/2 years. Even the most expensive ones just aren't worth it; too many internal plastic parts, & very noisy.
The older Singers from 1960-mid 1970s and earlier are wonderful machines. By about 1980 they started to go downhill, the company was bought by someone who was only after a profit; rather than a good quality machine.
I bought a new Singer in 1986 and had trouble with it from day one, the store wouldn't take it back and refund my money.
