I have a Brother PQ-1500, which is similar to the Juki, I love it!! I just got a Grace frame, but have not had time to try out the combo together...as far as stitching, my Brother does an amazing job...I do have to agree with tatavw01, in that I wish it had a zig zag stitch...but I also have a Brother PC-420, which has way more stitches than I would ever use!!
Regards,
Kif
