I purchased this Kenmore when I decided I wanted to start quilting, but I got it during their friends and family and also have an additional coupon for it so I picked it up for much less than it's current price.

They have a nice quilting pack online at sears which I believe will have all the things you need. :)

I have had one issue with mine, the pedal seems to have a little issue with being reliable, but they are sending me a new pedal to replace the one I have. Hopefully that will fix the issue. It an annoyance, but they have been very friendly and easy to work with.
The machine itself has been EASY PEESY to learn on. And I would buy another one.
