I just purchased the Baby lock enlighten serger. I do a lot of scarfs, as well as I need it for sewing (or serging) the sides of my Embroidery tote bags. It is EZ with the air threading. At first wasn't sure of it, so went back to the dealer. It was me, I had it threaded right, but my problem was I didn't have the pressor foot down. After another 10 min tour, I was up and going ok. I love all of my baby lock machines, very dependable.
They gave me a thread in plus for that one Baby lock will give you another gift card. I don't need a fancy serger, will take some lessons to see if I can do something else with it.
