One of the series is on my want list. The 320 would be ideal, next either the 319 or a 206. the 206 since it's the first Singer domestic zigzag machine the 319 or 320 because I think the typewriter key stitch selector is cool. I like the 306 too, I just like the others more. I was surprised by how sturdy these machines look in person. They could be mistaken for an industrial model easily. I also love the wood base that the 320s have. Beautiful machines guys.
