Ummm....So far I really do like my 590 except for the 9mm feed dogs when piecing...but it seems like a solid machine and I sure can customize it to the things that I like. Like the "hover" feature that lifts the pressure foot a little and leaves the needle down when I stop. It makes it so easy to do applique for the turning. It also has a knee lift if I don't want to use the hover and it has really small adjustments for stitch length and width. If I change stitch length, it remembers that until I turn it off for the day but if I want to save the setting I can in a menu or if I want, I can make it a default setting. Yeah, it has a lot of bells and whistles. I haven't really had any problems that were not me just not understanding how it works. For embroidery, I can switch the thread colors from the one the design was digitilized in by the designer to the color number closest to it in my collection of RA thread which does save a ton of time. It does have a stronger motor in it also so it will stitch through several layers of fabric. If I tell it the type of fabric and what kind of stitching I am doing, it will auto select things like the stitch length and foot pressure. It also has an "ECO" mode that just simply turns off most of the lighting in case you want to take a break. When I come back, I just touch the screen and it wakes up with all the same settings. I think I am liking it the same if not more than my beloved Viking D1 which I had for years before the screen died on it. That machine, I sure did get my money out of it using it for everything from piecing, to making drapes, to making some clothing, bags, ect. I do like it better than I did my 440 and my 630.
