I have two machines currently; a generic-brand machine called a 'dressmaker' with that was not new when my grandmother gave it to me it fifteen years ago (best guess is that it is from the late 70s/early 80s), and a Standard rotary treadle in working condition that I need to order a belt for.
I do most of my quilting by hand, but I have my two machines in separate rooms. My dressmaker is in my spare room with a door that shuts, so I can sew to my heart's content without disturbing my family with the noise and fabric mess. The treadle sits out in the family room, to be a conversation piece and let me work on my hobby without shutting myself away from the rest of the world.
In some ways I am glad my budget is so small, or else I would have a house stuffed to the gills with old sewing machines I couldn't walk away from!
