If you have not decided on a light weight machine to take to class, I highly recommend the Janome Platinum 760.
The 760 has needle stop up/down, a speed control bar to regulate how fast or slow you wish to sew, many, many decorative stitches including blanket stitch, and hand quilting stitches. You can purchase an optional straight stitch plate, free motion quilting foot and walking foot. The 760 pieces like a dream. It weighs about 12 pounds,yet has similar features of the 3/4 size Berninas. It does not vibrate like the cheaper machines or the older Janome Jem. A video on Utube is what sold me on this little machine. Then I tried it out at my local dealer.
Believe me, I am a loyal Bernina owner, but wanted an inexpensive machine to take to classes. Check out the video, if you haven't purchased a machine, I hope you give this one a try. Good luck.
