This question comes up in my brain often.  Seems to me that it's much
cheaper today to implement an electronic selector circuit with a pot and an
MCU with an ADC input.  You get the added bonus of the smarts of an MCU.  

If only there were pots available with a series of equally spaced detents to
give the feeling of a selector switch, we'd have the problem solved.  Anyone
know of pots with detents?
