So far I have about 5 gauges, and they vary by about 7psi across the lot. Has anyone found a really good pressure gauge? I'm tempted by the internal pressure gauges next time the skins come off the rims but for now I need something accurate. My other option is setting a set of staun deflators to my desired pressures and just overinflate and deflate down to the right pressure. If they're accurate +/- 1PSI that is.

Any other suggestions/ideas?

 

Best gauge I have been able to find under $100. I have been using this guage for over 5 years.
