I believe the Janome Jems run about 12 lbs. Lots of good comments about them from quilters. There are different models of this machine, ranging from those with just a few features and those with a lot of feathers and decorative stitches. Here is a link to just one of them on Amazon:

A lot of quilters buy these to take to classes because they are very portable (handle on top too).
