I have the Quilt Expression 4 and love it. It sews like a dream and is very easy to quilt on. I am just learning to machine quilt and have been very pleased with its performance in that regard. Mine seems to be kind of picky about what threads it likes but that could be more a function of the fact that up till now I haven't done very much machine quilting. I do like using a bottom weight thread in the bobbin so that you don't have to change bobbins so often. It is a beautiful machine!
