You ARE crazy if you're thinking about tossing this machine because of bobbin problems! That is a great machine and given a chance will sew circles around your old Kenmore. Given a chance you will be very pleased with it. Sort of sounds like me and my first "stupid computer". It just wouldn't do anything right. I couldn't figure out why it was doing what it was doing, either. Of course, in the end, it was "operator error". Please have it looked at first and get a brief lesson on how to operate it. If, in the end, you decide to shoot at it, please put it up for sale somewhere near me!!!
