I have a Babylock ovation serger which I love. I used it a lot when I was sewing garments for my grandaughters. Now since they are too old (17 and 18) to wear home made clothes, I don't use it nearly as much. There are several models with the jet air threading. My advice is to go to a Babylock dealer and check them out and test drive them. Then you can make a decision about which one is best for your type of sewing.
