I bought an aluminium 201K a few weeks back from ebay (for $17). The main problem was the light. It was a Canadian model (converted to local voltage) and I couldn't find a light bulb to fit it (screw in type, and larger than the usual one).
So, I had one in the shed from a 96K industrial. Screwed it onto the old light mount and soldered it into the motor's electrical block. Fitted it with a 15W modern fluorescent bulb which is supposed to be equivalent of 75W. After it warmed up it's definitely impressive, and doesn't get too warm.
Had to turn it off to take a proper picture because it was so bright.

The head of the light can be swivelled

From the top. Mounting it was easy, just sandwiched the original fitting with one on the light.

Turned it off for this. It's been angled back and moved so I don't get light directly in my eyes, but I've never been able to see the work this easily before so very happy and keen to get back to sewing
