Numbers are all good and fine, but for at a glance, typically Analog gauges rule not because they have big numbers, but because it's all relative.
Relative placement of the needle that is. As long as you can view the relative location of the needle at a glance, most guages are fine.
Though I agree, I'd have to see the quad Westach gauge in person or in a picture to make sure the scale isn't so small that even relative position wouldn't tell you anything.
I'm still playing with the idea of a information display that tracks data from the EEC-IV as well as additional sensors and places it all in one LCD touch screen panel. But that is for the future when I have plenty of time, and a little more money.
