I didn't have the Bernina frame but the grace and I used my Bernina machine. For me it was not practical to take my machine off every time I wanted to work on piecing. Because I worked, it took leaving the frame/machine up all the time since some days I only worked 15 mins on the quilt. If you have another machine you can use for piecing that may be your answer. The price and quality of the Bernina frame is a good deal.
