I've got my trusty Brown and Sharpe 6" digital, a 48" vernier and a CMM
I have had the cheap chinese digital in the past. They go though batteries like mad it seems, and fall apart easily. Buy a good one and it lasts and lasts. I bought my B&S about 7 years ago and it is still as good as the day I bought it. Digital also makes it tons easier to to Center to center dims of like sized holes.
