My Bernina came with a small extension table. However, if you are looking for a better surface for FMQ, especially for larger quilts, you might want to think about making this kind of extension surface for your machine (parts 1 & 2):

Dh built mine for me (it was a little more complicated because of height and shape of my sewing machine), and I really like it for machine quilting. For piecing, though, the extension table that came with my machine works better.
