Case in point being the price difference between the UK and the US - are you saying that you bought that Michelin gauge for $20? The cheapest I can find it here is £25 - that's $39, and I thought I was going to have a good day !!!
As a matter of interest, what did you use to determine the gauge accuracy?
You can buy that gauge off the internet. 40 bucks sounds expensive. I used the digital gauge as the reference as, repeated measurements yielded the same numbers. Then I measured the other gauges off of the reading I got with the digital gauge. This is all on the assumption that the digital gauge is the most accurate of the 3. Considering it's measuring in increments of 1/10 of a PSI when the others are using units of 1 and 2 respectively, I think it's safe to make this assumption.
