I have the HQ Sweet 16 and tried the demo at the store where I bought it. I was excited to try it, but was a bit disappointed. Maybe a learning curve, but it seems like I do better without it. It felt a bit choppy and the stitches didn't look as nice. Could have been a tension issue and I may go back and try it again now that I've had a chance to use my machine a bit more. I would definitely test drive before purchasing.
