I use my domestic machine for quilting. I love what the LA can do, but I'm too cheap to spend money on that kind of quilting.
It takes practice, especially if you are working on bed size quilts. The maneuvering is one of the toughest parts. If I ever make a king size quilt, I'll probably bite the bullet and pay to have someone do it on their long arm.
But, for now, I have fun practicing free motion and using my walking foot. I've even done some quilting in the hoop which is fun too!
