I have an old electric Singer, and three Brother machines, one NX200, one NX400, and one QC1000. I love all of them. The Brothers come with lots of "feet" and other extras, plus extension tables that fit on the side. The QC is my favourite, the lighting is really good, it has a touch screen (including drop the feed dogs), several needle positions, and in-built scissors. It has a knee lift which I don't use, because it can be set to cut the threads and raise the pressure foot with a push of a button. I also like being able to slow down or speed up the stitching by sliding a switch.
Good luck with your hunting, I hope you get a machine you love.
