I just got this machine is January! I love it. I replaced my other brother that i had for 10 years, still works great but I wanted more stitches. I have FMQ on it. I have found that it is very picky about thread, the thread has to match the fabrics or tension problems with FMQ. Piecing doesn't seem to be a big deal with thread. I had to set the tension on 8 with FMQ to avoid eyelashes. Mine came with all the extra quilting feet which was fabulous!! I tried to put my walking foot from my other brother on this one and they are not the same broke the needle.....the opening for this one is bigger on the walking foot. Just thought I'd share. I love it but the throat is very small still I don't know that you could do a king without a fight but I would love to see it if you do!!! I found that it uses a 75 needle vs the 90 I usually use. Hope this all helps if it doesn't please note mine is hooked into a transformer because i live in German housing so it may just be my machine performance. Happy Quilting!!!
