I learned on a Nolting funquilter at a store where I worked. When i retired I bought a used HandiQuilter 16 for $5,500 about 3 yrs ago. "Harriet" has not given me any trouble once I figured what threads she liked.
The only other thing is I have not been able to find how to change the LED lights on the front handle bars, but I sew from the back...still I need to work on getting those lights fixed.
