I love it when I can use the Federal Reserve consumer price index calculator!http://www.minneapolisfed.org/index.cfm
OK, so $250 in 1952 would be .........$2,093.96 !! Of course, one could never sell it for that amount now, but it does put the "new" price in perspective.
Your mom's $250 in 1952 works out to be about 37 cents per month over the last 56 years- good deal!
FWIW mcgintie, I doubt your machine is a 201-2 with the potted/gear driven motor. Not too many of those sold on your side of the pond. You can probably look up the serial number on the Singer website to help you ID the machine.
Since this original post was about a PINK machine, I thought I'd share a photo of a pastel AQUA machine that is on my bench now. (obliviously the photo was taken last summer- no snap dragons out there now!)

This morning, I was testing the machine on a variety of materials (leather, denim, regular cotton, and making some furry dog toys with it) and when DH walked by he commented on the machine. He usually pays no attention to any of the machines, but he was impressed with this one. Go figure!
