I have a Baby Lock Quilters Pro machine on a New Joy frame, which is probably about what you are looking at. I have no problems with the amount of quilting space usually, but when doing larger quilts I do have to be careful so I get the whole pattern on the available space -- which is around 5" wide, with about 4" really useable space. I like using pantograph patterns, because then you get even pattern overall, or I do my own style of meandering swirly pattern that is OK with varying size loops and swirls. My frame sits on the floor with the machine on a little platform that moves in all directions.
