Those machines are good for very simple, straight stitching; repairing a hem, etc. I had one of those and it tore up within 4 months, because I was sewing patches/stripes on USAF battle dress uniforms. They are not meant for heavy duty sewing. But for sewing a simple quilt, or pattern, they're ok. Just make sure you keep it lubricated, and never sew over pins (
like I did.. der! that will knock the timing out of whack and make the stitches skip/loose.) and it should last you for a while.
I'm sure you already know that though...just in case someone else is contemplating buying one; I thought I'd share my exp. with them. Like cars, I seem to tear up sewing machines quite a bit.. so far, my Janome has put up with me the longest.
