I share the same view as you, this is the main reason I started this project even if I don’t own such a board.
Those boards have very good value and should be kept working a lifetime.
Also old boards like the M65-A have a nice old school design that makes them interesting both visually and (probably) sound/feel wise when you are typing on them.
You could make the PCB ordered and assembled at JLCPCB, it is rather acceptable price wise and even more if you know a few friends that want a PCB as well.
