Baby Lock is the perfect serger. I have a Evolve, Evolution is the newest version. It has 8 threads and does overlock stitches. Another option,depending on your needs, is to purchase a 4-thread Baby Lock (Enlighten or Imagine),and a separate overlock machine. the advantage of having a separate overlock machine is to have it set up and ready to use if you do a lot of overlocking. This is my second Baby lock and I would purchase another one in a heartbeat...if I needed one!

The ease of threading and no tension disks is a winner!

Happy Shopping!
