HQ 16 with pc-quilter for computerized quilting. I've had it for about 3 years and done about 20 quilts on it. I only do edge to edge patterns, though, because of some health issues. If I didn't buy it, I would have gone broke getting my quilt tops 'done' by someone else. I had 2 done at about $200 a piece, and didn't like the result.
Sometimes I still don't like the result of the quilting, but now I have only myself to blame.
