I bought the Sapphire 830 about 2 yrs ago for 1199.
I like it and have not had any problems with it.
It dosnt have an auto thread cutter which would be nice. But it has everything else.
Some times I wish I had gotten the 850 for embroidery but it was more expensive.
Bernina is out of my price range so could not get the stitch regualtor I very much wanted.
The ten inch throat is wonderful and have quilted many quilts with ease.
I havnt used the fancy stitchs much but plan to. Im not impressed with the instruction book. Took lessons when I first bought the mach but have forgotten them now.
Be sure and use the 1/4 inch screen which I did not know about. Now I can adjust for scant 1/4 inch.
One thing I dont like is how low the top of the machine is for threading and changing feet. It is hard to fit your hand in. It does have a threader but havnt learned to use it yet.
