I think it won't be too hard to find a walking foot. And because she is a mechanical machine, she can easily be fixed by anyone. I wouldn't trade my Juki for anything. I might someday get a fancier computerized machine, but Juki stays!
On the frame, with the Juki- you have between 4-6 inches of quilting space. So with a shorter arm, you will have even less.
I know that many people do not like a stitch regulator, but I really appreciate it- it allows my stitches to be uniform even if my speed is not, and that is golder for me. Maybe I'll outgrow it, who know?
She should have come with a walking foot. Did you ask the seller?
I love piecing on the Juki as well- so smooth. She's my girl. No fancy stitches, but what she does, she does very well. Just remember the magic words: Juki likes oil.
