So Bernina made cast iron zigzaggers then? I have a "modern" plastic Brother machine from Walmart that I use for my appliquing but when it dies (which it will, lol!) I want to replace it with something that will last and I can service myself. I'm kind of looking at the old Kenmores and Necchis too. I've really grown to appreciate these old machines that don't die as fast as the cheap plastic one-- even the not so cheap ones!
