I've owned a Babylock Allegro for almost two years now. I haven't had any problems with it. I love the big throat and the ease of using the machine. I always clean out the race, use good thread and have never had any problems with it. I've heard complaints about the Allegro but it's usually operator error, they didn't read the manual, can't get it threaded, etc. I've quilted a lot of quilts on mine and have three more in line to quilt this weekend.
