I've had the 830 for 2 years and absolutely love this machine. For creative sewing and embroidery, it absolutely to die for! This is my "go to" machine because what it will do... you can't even begin to imagine until you've used one for awhile. Everything can be adjusted, altered... truly amazing!
However, if you're primarily a quilter... I would also choose a longarm over the 830, and a nice basic sewing machine.
