Tried to edit my post above but the time frame elapsed The Bernina Q20 was quite a bit more smooth than the HandiQuilter or Grace Q’Nique but the price point is also nearly double. Since I’m only planning to quilt my own quilts I can’t justify spending double without a good reason.
The HandiQuilter seemed to vibrate less than the Grace Q’Nique.
Another note - I will not be getting the computer assisted quilting at this time but it may be something I want to add in the future.
To upgrade later to the computer system the Grace is approximately half the cost of the adding a computerized system to the HandiQuilter.
