Yep it is a close copy Dan, the Mitz 410 is a close knock off with the exception of the feet being a little longer. Most people swap them but they are a little different.
Welting alot of time exaggerates needle issues even with the right feet.
I tend to agree that if you are a newer sewer or dont want to do some of the other types of bed set ups. The investment of 60 bucks worth of feet, a first sew and a second sew set, tend to be well worth it for the hassles. Just my two cents though.
