Learn to sharpen your old saw. It isn't difficult to learn. There are
several sites, Disston, Stanley, etc. that I believe have sharpening
tutorials. You'll need a vise, some scrap boards to sandwich the saw in
the vise, and a triangular file. A saw set might be needed if it's in
bad shape. Take it to a saw shop for setting if needed. I don't use
mine once every ten years.
Once learned, it is an enjoyable [and possibly profitable] pastime.
