My Elna only uses Schmertz needles. She intensely dislikes Singer needles. My slant needle Singer 301s both aren't fussy. Right now they are using an off brand I bought on ebay at $9.99 for 100 needles. The vintage Montgomery Wards machines don't care either. The Necchi has sewn with these "Orange' brand needles and did a nice job FMQ. So, of all my machines I've used, only the Elna is fussy.
