The 1948 machine looks very nice Suzie, I hope it can be improved upon. I hope to find a 201K2 with a similar art nouveau (deco?) decor. I'm thinking I have to import one from the UK, though I know they were sold here too :- )
I bought an electronic pedal, but I went back to my button controller. Mine is fine, doesn't get hot, and I developed a feel for it. The speed control is good too, and I rather have the original when there wasn't a noticeable improvement. I think peldas are very individual, though they should be serviceable. Most of the YDK pedals on ebay.uk are actually the same carbon resistor type as the old bakelite pedals. Not all of the electronic ones are that good either for some reason, and these should in theory (!) be much better (from stop to full speed and little inbetween).
