I have 2 Babylocks and a Janome, all with thread cutters. I don't use them all of the time because none of them "tie" the threads when cut, and they all leave thread nests on the underside when I start a new line of stitching. I should get in the habit of using leaders I guess. I agree with JustABitCrazy - the auto thread cutter is not something that I am especially excited about anymore.
