has anyone ever tried to put a digital speed/tach on a gs. does anyone have it?

There have been a couple of threads regarding mounting a bicycle computer on the GS, but I've never seen anything about an electronic tach.

The bike computer (Sigma brand recommended; tops out at over 100mph) contains a highly accurate speedometer, odometer, trip odometer, clock, stopwatch, and other bells and whistles depending on which model you choose.  It'd be nice if one incorporated a thermometer, but I haven't seen one at a decent price.

I'm not sure about the functionality of a digital tach on such a quick-revving engine like a motorcycle.  Most tachs on bikes with digital speedos are still analog or analog-type pie or bar graph displays.
