Oh a $200 greddy electronic gauge, beat out the $50 mechanical autometer ?
Gimme a break, realistically the .5psi, maybe 1 psi, isnt going to cause anything magical.
Basically. Buy what you can both afford and you think looks good. Then go figure out how to calibrate it.
Lab 101. Get thermometer. Put it in boiling water and ice water and take readings. Plot trend of how far off your thermometer is. Now you can start to use it.
