Thanks, everyone. It looks like most of the same brands are showing up here that I found searching Amazon and Google shopping.
That does help. At least in that I tend to trust people here.
One thing I have learned is that any gauge that says it is compliant with the ANSI standard has 2% variation in accuracy. That means a 30 psi reading can be .6 psi more or less. So it seems like a gauge that is marketed as being any more
precise than ~.5 psi is not really necessary.
I'm looking at a few different ones. Lots of good choices.
I'll keep you posted..
