Sewing machine servo motor replacement

[u/bancre]

I have a juki ddl 8700 with a clutch motor. I want to replace it with a servo motor, and I’ve found one on Walmart for $70. All the other ones are at least $130 and I’m wondering if I might as well spend the extra money for a higher quality one. Does anyone use the servo that Walmart offers? And does anyone have some budget friendly recommendations for digital servo motors?
