I started off with a HQ Fusion, added the robotics 2 years into owning it and then sold it just before the pandemic. I purchased a used 2017 32in Innova that had Mach 3 and the Embroidery module as well. IMHO, HQ has a steep learning curve for the robotics. Innova on the other hand is very user friendly and easy to use and set up, and I have had zero issues with it, so happy I purchased it.
I agree with looking at Longarm University for used machines, you will more than likely find a good deal, and Cindy at Longarm University does longarm classes too, she is a wonderful instructor!
Let us know what you decide, you will have so much fun!
