I have a 301 in a cabinet just like the first Craigslist link above... only mine is black and a 1937 model. I love it! It sounds wonderful running, and does the nicest straight stitch, always. They have a little fold up handle on top, and you can lift them right out of their cabinet and carry them to wherever they need to go. They only weigh 16 lbs, which is only 4 more than the old featherweights. But they are a full-sized machine. They are also strong and powerful because there is no belt-- they are gear driven with a "potted" (internal) motor. It's pretty rare to find a 301 for sale.
Sales pitch done.
