I have brothers but...consider if you have to add an attachment to embroider...I didn't like taking one off and readjusting...guess I am spoiled so I wound up getting an additional machine to do my quilting and sewing on...so I can do both at the same time...
I didn't know enough at the time of my first machine purchase to think about this. So you may want to get a more simple machine to sew and quilt on and use the other for embroidery.
If that is an option for you.
You would like the bigger harp for quilting!
