The post you linked to has been removed. The one downside with Craigslist is that a fairly high percentage of the "deals" on their site are stolen goods. I have a friend who's a reporter & did a story about it (wish I could find the link). So in addition to everything else I look into when purchasing something from Craigslist, I also type the serial number into Google along with the make & model to see if anything comes up with it being reported stolen. Since we started doing that, our church group has found 5 items that were stolen that we were able to report to the police and get returned to their rightful owners.
Hope you find another good deal. I love vintage Singers!
