If off, go try out all the machine/robotics that you can before plunking down your money. I started out slowly with a 9" Viking MegaQuilter on a Grace Pro 10ft, then added PCQ robotics which worked fine but 9" doesn't give you much room to move around in so after trying out a friend's machine she had stretched to 18" (Juki 98Q) I was hooked and found a used Juki machine and put my name on the list to have it stretched. Sorry folks, I'm sure that man has long since died as his health was not good back then and that's been 14+ years now.
Anyway, when I started making larger quilts I decided someday I wanted to go larger with the machine and frame so went to my 1st quilt show in Des Moines, IA. I played with every machine I could get my hands on. The friends I went with, one of them had an Innova plus by that time I had moved up to MQR robotics which she also had so I knew my robotics would work on this machine. Came home with the brochures, told my mother what I saw and wanted, later she gave me the money to order it as she wanted her quilt done quickly. I did have to upgrade my MQR robotics so I took it down to TX where the folks were and had it done.
Years later, he went MIA so no longer support for the robotics and it started giving me fits so I started searching for another roobtic system similar to what I was used to. I remember the robotics for the Innova used a cable you can to disconnect and I didn't want to have to do that all the time and finally I cam across the IQ, watched every video I could get my hands on and decided that was the robotics for me.
Also with the Innovia, you have 24/7 phone customer service and most times Michael on the other end could walk you thru just about anything. Also with the IQ there are videos to help you with most any problem you might have with it. Just my take on this subject.
But again, try them out. Take some fabric with you and even threads you have on hand to make sure that machine will stitch with it. I found with my Innova, I can used just about any thread I throw at it including embroidery metallic threads.
