I would like to echo everything feline fanatic said. I also have the standard stitch regulator, 12' frame, 26" machine. I do not do pantographs, only free motion with and without rulers. I am considering adding robotics, although I might go with MQR rather than AutoPilot. (I haven't seen MQR yet.) I considered Navigator, but I asked at a quilt show what the differences were between it and AutoPilot, and it was clear to me that the huge difference in price was because of a huge difference in capability. At this time I'm not quilting professionally. I've had my machine about 4 years, and I would love to have a new one with some of the enhancements that have been invented since I bought my machine, but if I ever buy a new longarm it will be another Innova.
I also called for help a few times when I first got my machine, and it was always immediately available. I haven't had to call for quite a while (knock on wood).
