If you can get a pump with a small gauge, great; but my experience shows that it is not really necessary, assuming you have a floor pump at home with a gauge. So my pump for the road does not have a gauge, I gauge it by squeezing and comparing with the other tyre. That's good enough to get me home and if necessary change the pressure with the floor pump. The road pump is very small and can do both types of valve and has a air tube to protect the valve during pumping. Just drop it in a pocket. There is a MTB version too, which will do lower pressure.
With the hp pump I recommended it is possible to burst a tyre if you have wide tyres. It can go to 160psi easily but it will take you a lot of strokes to get there. You will probably get tired of pumping before that happens. If you have old cracked wide tyres, then there is a real possibility to explode the tyre.
