I've had one since August and really like it. I don't have room for a longarm but wanted a better way to quilt larger projects, and the Sweet 16 fits my needs very well. I don't have the stitch regulator, I just took a little time with practice pieces to get used to the feel of the machine.
The Yahoo group for this machine is a great source of information:
