Nova Montgomery is a great source for FW information and she sells machines. She has visited our guild 3 times and I enjoy her presentations.
There is a Yahoo group for Featherweights that is very informative. I believe Graham Forsdyke is the moderator. He is located in the UK, but he sells FWs to the US, too. Google 221 Parts (a very good site for parts & accessories); April 1930's (sells FWs, parts & accessories); David McCallum (they are retiring next month so will no longer be selling,but he has a great book/DVD combo on the care and maintenance of FWs); and Glenn Williams (parts & accessories).
FWs are the least intimidating machines you could ever hope to own. They were built to last and to be easy to operate. They only have a straight stitch, but they are wonderful to work with. I hope you find one.
