I love my Juki TL2010Q and have not had any bad experiences like the one described by charlottequilts, however, I have become aware that the inside of the bobbin case has a little black clip-type mechanism that is a lint magnet. I inspect that little clip every time I change a bobbin. I brush every bit of lit out of it EVERY time. That machine is amazing. I prefer it over my Elna 3007, a classic Featherweight and a Janome 9500 unless I need embroidery or fancy stitches.
