I have one machine with the thread cutter and I love it. It's the Janome MC6600P. It has the knee lift which I do not use. It also had the needle threader that I use from time to time. My favorite machine is my Singer 15-91 that is the machine I learned to sew on in 1962. It has the knee control so that is why I don't use the lift on the Janome. In fact, on the Janome I use the button start more than the foot pedal. And since my Singers (I also have a FW) do not have needle threaders I usually thread the Janome before I remember the threader. The needle up/down is very nice too.
I have the Husqvarna Designer Topaz 20 embroidery/sewing machine that also does not cut thread either, and I wish it did, but I use it mostly for the embroidery.
