Dandelion, have you considered a vintage Singer 301? They are full sized machines, weigh only 16 pounds, and sew a lovely stitch. I take mine to all my classes, retreats, and sewing circles instead of my Bernina. I think those FWs are just adorable, but I couldn't find any around here at a reasonable price, so I went with a 301 (well, two actually) and have never regretted it. I love sewing on it.
On the modern side, I've heard good things about the Janome Gem, and my sewing partner brings her Viking +1 (??) every week. I just wanted something simple, without electronics.
Whatever you decide, keep us posted!
