Great machine! I have had mine for two years now. No problems whatsoever. Not fussy about thread. I have used 12 wt cotton and it looks gorgeous. I have also used nylon invisible thread, and only needed to adjust the top tension. The only minor drawback is that the two FMQ feet which come with the machine are of the "hopping" variety. I purchased a Sharon Schamber foot. It works on the Juki, doesn't hop, and can be adjusted to glide over the quilt top. I recommend this machine. Great value for the price.
