I have had my Juki's for almost a year - a 2010Q and F600. I bought them both online and have had no problems with either machine. I kept the original packaging so that I can mail them for service if and when the time comes. I clean the lint out regularly.

I do most of my piecing on the F600. I love being able to break it down into a free arm and it has a gorgeous buttonhole stitch. I've used a few of the deco stitches and enjoy using the serpentine stitch for quilting small projects. I have yet to adjust the tension and it is not picky about thread. I think for the $$ it is a great value.
