The thing about EM versus SS is the amount of work you can do yourself on the machine. I compare an EM to a typewriter and an SS to a computer. The EM is mechanical and can be sorted but the SS is computerised and uses technology not available to us all to repair. From a repair viewpoint the EM is able to be fixed by anyone but the SS requires knowledge and tools not available to everyone. Don't get me wrong...the EM is a computer but it is based on a technology we can repair without specialist tools or knowledge.
