Tyre pressure gauge - accurate and consistent one required!

[Captac007]

Hi all
I'm seeking a consistently accurate tyre pressure gauge for road and track use.
Happy to pay up to £100 if its a good one. At the end of the day, there's only
four small tyre footprints that stop the car from turning into an aircraft!

Anyone have recommendations, either analogue or digital? Ideally one with a bleed valve

Thanks
