New Singers are terrible. Brand new one sent out for repair about than 3 months after purchase (hardly used it as it was a back-up). (Has to pay shipping - and had to fight to get them to honor the warranty). Parts are still falling off - screws, stitch guide, whatever. Sounds (clunks, rumbles, squeals, etc. serenade me as I stitch :)
All my older machines (Kenmore, Singer, etc. are still running strong - no problems.
