I have TL Queen Quilter with QBot. I am grateful to have the set up, but I have to say Lizzie can be temperamental. I am learning to get along with her more & more. The one thing I really wish I had though is a machine that would stop stitching when I stop moving it. Lizzie slows down to a slow continous stitch. Also, I would like better maintenance manuals. Can't really take these machines in for repair or maintenance, so you will be doing lots of that on your own. Good luck with your search.
