If you like vintage machines, but are not in the market for a featherweight, you might try a Singer 99, or 99k. They're a 3/4 size machine and are just a little heavier than a FW. I love mine. I has the prettiest stitch I've ever seen. They sometimes come with cases, although they are usually rather worn. I'm planning to recover my case and class it up a bit.
