I do all my own quilting on my regular size sewing machine. I usually stitch in the ditch or along the ditch with a fancy stitch or around certain shapes in the quilt. I have also done free motion quilting by dropping the feed dogs. I have made a couple hundred quilts including about 20 queen size. The quilting is not fancy but it is done.
I have never hand quilted. If that was all I could do, I never would. There are lots on here that hand quilt and many many of us quilt all our own quilts on normal old sewing machines.
