I did have the Ruby, loved it and then a yr later traded it in for the Diamond Deluxe, love it so much. No tension settings, it lets you know what needles to use for different stitches and fabric, great at embroidery. You can adjust the speed which is really important on some things that it does. I've had mine for a few yrs and love it so much. When I take classes and they supply the machines the one thing that none of them do and would miss is that when I push start, it lowers the pressure foot and starts, the others beep at me because I always forget to put it down since mine does it for me.
