Some folks recommend the Janome Mini Sew ($59). Weighs 5 lbs. Has straight, zigzag and reverse. All plastic machine, so that maybe a draw back. Some folks love this machine, others think it's junk. Haven't used one, just saw reviews of it. Thinking I might buy one (
http://www.HomeDepot.com) to use for taking to classes. People think this is a good machine for kids to learn on.
