This is good reading, and perfect timing for me. I am hunting for a Singer 301 with no luck around my area, (southern Idaho.) Thrift stores around here don't get vintage sewing machines, apparently, according to them. I found out at least one reason today... The thrift stores take any vintage machines in to the local sewing repair shop owner, who donates his time to go through them, fix them, and sell them for the thrift stores. I saw a 99k that just came in today, a 1952, I think it was. Box in sad shape cosmetically but solid. Machine looked good already, no rust, quite clean, it runs, it has quite a few feet, accessories, and manual with it. $75. Gulp. I use my machines, don't just collect, and while I especially want a 301, a 99 is on my "wish list," too.
I appreciate reading all the view points on this aspect.
