I plan to buy the Baby Lock Imagine and the separate Baby Lock cover stitch machine. From what I can see those are very reliable sergers. My Huskylock seized it's motor a few weeks ago and it is not worth the repair bill. Baby Lock has a dual duty machine that is both a serger and a cover lock, but it is necessary to rethread each time you want to switch over, my dealer has offered me a good price on the 2 machines.
