I have been using BabyLock machines for years, currently own Ellagante, Elure, Evolve Serger and just bought Juki TL98Q. I've been teaching machine embroidery and quilting classes at the local BabyLock store and most of my students have either a BabyLock or Brother machines. I love my machines and the only problem I've seen both in class and in my own machines is that the needle thread can get caught in the brass bearing and will cause the machine to seize. They best way to avoid this problem is to always cut your thread on the top of the machine and pull it out from the needle. If you have a thread that shreds or breaks inside, get a little flashlight and sewing tweezers and look for the wayward thread. I would be happy to help you with any questions, if I don't know the answers I know to to call to get the answers. BTW the Juki machine is the same as the Quilt Pro, they are both semi industrial and have a speed of 1500 SPM, are very easy to operate, easy to adjust tensions for 2 thread color quilting. The walking foot is heavy duty and has made me a lover of walking foot quilting and the compensating foot makes chain peicing quick and accurate. And no I don't work for the store and don't get commissions, just a huge fan.
