I have a Bernina 440 and the Bernina frame. I use my 440 on the frame. Sure, I have a very limited quilting space but I don't mind because I really enjoy the feeling of moving the machine over the quilt sandwich. Once I am fully recovered from my battle with breast cancer I will put my Christmas present, a Bernina 710, on my frame and use it exclusively for quilting. I have a bunch of them hanging over the frame rail just waiting to be quilted.
