Thanks for all of the feedback. Lots of good examples.

I have one of the mechanical gauges encased in rubber that I really have liked using. Its accurate and durable and has peak pressure plus tire tread depth gauge. The only problem is that it just started leaking pressure (won't maintain the peak pressure reading so I assume the button that releases the peak pressure is leaking). I might try placing a bit of rubber seal lubricant around the release button to see if that might help. If not, I did find an Earl's gauge set up in my brother's stuff that has bleeder and fill valves that may work as a replacement.

Thanks again.
