Thank you all for replying! I called my husband and wife chiropractor friends. She is a quilter and had the HG on a rail for a long time. Sold it and bought the Avante which she said rolls super easy compared to the other. She made a couple suggestions and then quoted her husband "You can get a lot of quilts quilted by someone else for a lot less money". So I'm still thinking it thru while I am totally reorganizing my room including moving my machines to a wall area instead of in the center of the room. I am blessed to have a younger quilting friend to help and do the heavy lifting for me.
