On Micpres i find it very nice to have a stepped rotary switch to controll the gain.
You know those cheap 12step switches. What do you think about them?
Like pointed out in the other thread, i want to check out the INA103. It just needs one gainsetting resistor. What role does the distance between the chip and that resistor play? I´m talking of the distance between the chip and the switch. Propably not much, right?
Or, maybe a solution could be to have some relais switching in different resistors right on the pcb. I remember some design where a small number of relais were set up, so that a large number of different resistances could be realised, just by the combination of a handful of series and parallel resistors.

I can´t find that schematic anymore, anyone have something simmilar?
Or any oppinion on this is very welcome!
