I am so sorry about your machine. It is really hard to lose an old trusted friend.
I really know how you feel. I was putting the binding on my nephew's wedding quilt when my 25 year old Pfaff started smoking. Filled the whole house with smoke. I had ceased up the motor. No fixing it. I had to find another machine fast. I spent the whole weekend trying out other machines and went back to Pfaff. I got a Pfaff Creative 4.0. It took some getting used to but it is the best machine I have ever owned and my nephews quilt got finished on time.
