I use a Lee scale and do not have any problems with measurements. I've checked it against other 'better' scales and got the same measurements. I've found the Lee to be more sensitive and reacts better to adding a grain of powder for example.
It is slower, but I do not load in bulk only 30-40 rounds at a time and I take it slow. You do have to have the three bars showing as mentioned by others previously for the 1/10th grain measurements.
I use this scale to load 3 rifle calibers (.30-06, .30-30, and 8mm Mauser) and my shotgun turkey loads. I just developed a load for the .30-06 of 51.4g 4064, Accubonds, Rem. brass, and Win. primers. Got .75 inch groups and load 33.5g 4064, Win. brass, Win. primers, and Speer bullets in the .30-30 to get 1" groups with iron sights in a Win. 94. I use Lee Classic Loaders for the rifles and my shotgun. I have a 7mm-08 I just bought, but don't have the rifle yet, so I'll have to keep everyone posted later.
Good luck!
