I have a 1955 Model 221 that I bought just a couple of months ago on eBay. Maybe not a great price deal, but it's in perfect condition and sews beautifully. I bought her to take to classes and retreats instead of risking my big Bernina (which is too heavy to carry anyway). Took her to her first class yesterday....what fun to sew on her!
BTW, her name is Mary Ruth...for my two grandmothers and what my parents almost named me!
