I have the Pfaff equivalent of the Viking MegaQuilter, with frame and Qbot. Either one Viking or Juki will work with Qbot just fine. However, your quilting space is limited to about 4 inches at the end of a quilt. If you have the money, get a larger machine. The HQ16/Avante/Fusion and Tin Lizzie 18LS/Queen/Ansley all will work with Qbot. I do wish, that I had the money for a larger machine. But when I do get that money, my Qbot will be able to work with the new machine, also. Whichever machine you get, you'll enjoy your Qbot.

Thanks for the advice. I think that the Juki is going to be my choice even if I get the qbot.

Thanks so much!
