I love mine! It doesn't do well with a 1/4" foot (the kind with the edge-it doesn't match well with the feed dogs) so I had to learn to use the screw-in guide, but wow. Mine just goes and goes. And I was lucky enough to get a complete set of cams with mine, so the possibilities for fancy stitches are endless.
It is kind of loud, probably because of the way the 'typewriter keys' are open and not completely enclosed, which means you can hear more of the mechanism than you usually would, I think. But still, I really like it!
