I got a Bernette 46 free for using the Bernina credit card. I actually haven't sewn with it yet. The plastic is mottled and cheap-looking. There's a new line of Bernettes, the 12, 15, 20, and 25, which look very promising. But none of the Bernettes take the Bernina feet. A Bernina 210 or 215 could shared feet with your 430, but they cost about $700 and are only about 5 pounds lighter. I bought a 240, which was recently discontiniued. I don't feel at all deprived, it has the solid, precise feel of my 440. For something lighter, I have a Singer featherweight if all I need is a straight stitch, or my kids' Brother HS 2000 if I want more stitches.
