The Organ HAX130EBBR needles are working well for me in both single needle and multi needle machines so I recommend them and typically buy 50 at a time.

You can buy other brands and sizes for your embroidery machine.  They will fit as long as they are for machine embroidery (not a serger or commercial SEWING machine.)  You can also use metallic needles, ballpoint needles or other specialty needles in your embroidery machine.  Here’s a video I’ve put together that looks at different needles and compares them up close.
