There is a Bailey owner group at yahoo. You could sign up and post any questions you have on the Bailey there. Theirs is a very active group of folks and are happy to answer any of your questions. I have a 15" Bailey, without the stitch regulator. Have had some issues, but am getting there! It is a very stright forward uncomplicated machine.
It had the arm length I was seeking and at an affordable price tag. Without all the bells and whistles, there isn't much to go wrong with it. Just about any sewing repairman can work on it, should the need arise. I have done about 4 quilts with mine so far.
