I don't have an illuminated knob. I installed the button LEDs myself (well with the help of Rob S and Patrick) as I didn't want to wait 'til next year sometime for one of Brians kits. Besides which, it's not terribly hard. Might have a go at a knob board when I get the time and the bits - doesn't look all that hard either. Hmm, I wonder if Brian could deliver the boards quicker than complete kits. Would save me a bit of mucking around ...
