Yes, the Consew servo is half the motor that the SewQuiet 5000 is. I did a lot of research before buying my first servo motor. I have two Sew Quiet 3000s and one 4000, and none of them has had as much as a hiccup in all the time I've owned them. The 5000 is an improved version of the 4000, and I think they want $199.00 for it with free shipping at Allbrands.com. All servo motors are not the same. I sew for a living, and I want something that is going to work. I wouldn't buy anything else, but what you buy is up to you.
No one lives forever, the trick is creating something that will.
