What is the best tire pressure gauge?
 

What is the best, most accurate tire pressure gauge and where can you buy it? My Accu-gauge is unreliable. I had a flat a while back ruining the stock Dunlop. I didn't even realize it was flat until I was driving along around 60MPH and it started shaking a little. $125.00 later I have decided to check the pressure at least once a week.
