I have found that my Viking Mega Quilter sews just fine. The only problem I have with it is the space in the neck. I wish that I knew more about them before buying it. I would of bought a 18" or 24" machine. One cannot do large designs when on the frame. I use Signature thread and Connecting Threads, a bit linty but OK. Maybe you need to find someone close to you that will help you out. Sometimes it takes more that one person to see a problem.
