Go on the Babylock web site and check out the Babylock sergers then you may want to find a dealer near you to go in and see a demonstration. You could also try them out. I have an older Ovation that coverts to a cover stitch that I like. However, if I had it to do over again, I would get one that did not do the convert to cover stitch thing and then get a separate cover stitch machine. Then you can leave the cover stitch set up all the time.
