I use the Jasmine Easy Spinner.

I like it because you can tilt it or rotate it to any position that you want. I'm able to adjust the height so that I can pull it in close to me so that I don't have to bend over it. If you have short arms I would go with the 14" hoop, even if you do have to move the quilt more often. Good luck in your search!
