I have the road morph G. It has a fairly accurate gauge and has worked well for me although I only run @ 90psi in my commuter tires.

I once stopped to help a road cyclist with a flat and he did not have a pump. He needed 115psi and there was no way that pump was going to go past 100. I have had no issues getting 90-95 psi with this pump - it's good in an emergency.
