Lots of sewing machines for sale right now (May 11, 2014) on this site:
http://minneapolis.craigslist.org/
They seem to be reasonably priced - I did not notice any "ridiculous" ads
There was a Singer 403 for $70. Looked like it was in good shape, there were also sergers, home and industrial, and a couple of commercial embroidery machines.
Much better selection than usual.
