I also have a BabyLock Evolve and have loved it for years. I upgraded to it specifically for the air threading, the self-adjusting tension and the cover stitch. It is not hard to switch from regular overlock to the cover stitch and I assume that the newer models are the same if not easier. I have used mine a lot through the years for everything from shortening sleeve hems (cover stitch!) to prom dresses to dance costumes to slipcovers and curtains. I would buy another Babylock in a minute if this one ever gives up the ghost but I don't foresee that happening.
