Have you ever heard the old adage about motorcycle helmets "Wear a ten dollar helmet if you have a ten dollar head"? There are some things that you get what you paid for. I've been told that the wider the range, the less accurate the gauge will be. To me, for most purposes, I need relative accuracy. Once I determine what the pressure should read on a particular gauge, I can measure if the pressure has changed on that same gauge. A man with one watch knows what time it is. A man with two watches is never sure.
