I have two sewing machines - both Singer. One is a school model that I purchased 6-7 years ago when I was getting back into sewing; the other is my mom's old machine from the 60s, I believe. I use it for my vintage buttonholer and as a backup. I also have a serger, and it's been a godsend! I much prefer the seam finishes in the clothing I made since I bought the serger.
Not planning on adding to the small herd, but I do look at thrift stores when I'm there.....
