This place has some choices of knobs and can add a button to it, and the prices arent bad. Where would the button be less obtrusive, on the top, or the 11:00 position?

This one is nicer with the hidden button, but would prefer all black.

This would be the ultimate if it wasn't so expensive and could have the Datsun logo.

I would like to find a knob with a flush button, or a covered one as second choice. Anyone got anything?
