I have what I think is the original Janome Gem. It is basically worthless to me. I have a dial with a choice of three stitch lengths. The smaller is too small, but great for paper piecing, the next is too long, and the third is a basting stitch. It's just too small and clunky for me! I paid $150 for it at Festival a few years ago. It did not come with a case.
I was lucky enough to win a BL9 with a small quilt that I made for a contest at our LQS, and it will replace my Gem. I can adjust my stitch length, and it is a little bigger, so doesn't bounce on the tabletop when I am sewing too fast for it. It will get it's major test drive at retreat in a couple of weeks.
