I too have the 440QE, which I don't think is available any longer, and I also have a 780. I have a Bernette 46 and also the 2000DME serger. I can't say enough about Berninas. But I wholeheartedly agree with everyone else here that the best thing to do is to go to the dealer and test drive a few different models and compare the features. It might take you a couple hours, but well worth it in the long run. You will be happier! Good luck!!
