My frame is an Imperial and it took the professional installer 6 hrs to put it togather.
It works very well and the carraige glides like it is on air.
My strait stitch Baby Lock Jane has a stitch regulator that I paid $500 for but love it.
I have to save up for a long arm as the 9 in throat is a real hassel to use.
Learning to use a long arm setup is enough without having to contend with a small machine.
