I also have an Innova. Because of the way the frame is designed, you have as much room to quilt with a full take-up bar as you do when you start out, and you don't have to make any frame adjustments at all. However I would advise getting 26" rather than a shorter arm. I've never heard anyone say they wish they had a smaller machine, but many have commented that they wish they had 26" rather than 18".
