My 1st quilt machine was the Viking MegaQuilter 9" but on a Grace Pro frame. I picked up the PCQuilter robotics then upgraded to the MQR. Finally changed machines but kept the same robotics and frame........Juki 98Q stretched to 18". Finally moved up for the last time to an Innova using the upgraded MQR. Now I'm moving on to IQ with the Innova. I love this robotic system as I can record my own patterns and keep them for later as well as use patterns I already have. This system also has the thread break sensor so if the thread breaks or the bobbin runs out it will stop the machine. I have hand tremors so FM is pretty much out for me. I purchased rulers to try but have yet had time to do that. I love robotics but if I do need to do FM or I allow someone else to use my machine that does FM its just a flip of a switch to take up the gears. Wish I could do FM but its just not in the cards for me. Thanksfully we all have options that work for us.
