If you're going to a quilt show I'd also check out the Innova booth. They have various sizes plus a sit-down model to choose from. The customer service is to die for too. Though you won't find this robotic system at any of the quilt shows at this time, you might want to check out MQR online at..........................

This robotic system can be installed on most of the quilting machines/frames. I have one on my Innova and love it and its at an affordable price too.
