I have the Bernina 220 and just love it, it is a workhorse and can do quite a few 'fancy' stitches, dropping the feed dogs is a breeze and it does FMQ nicely as well as everything else. There are other pricey Bernina's and some specifically for quilters, it all depends on how much you want to spend. A quality machine will cost $$$. I recommend you go to a Bernina dealer and see and test the machines out for yourself.
Kind Regards,
