The original Dillon Terminator is a good scale, but they switched scale makers and I don't know about their current scale? You can read something about this at
RSI's web site, here. This is worth looking at if you are not familiar with digital scales as it discusses some of the issues like digit jump. RSI sells the CED Pocket Scale, which works extremely well. It's only limitation is its 500 grain capacity, which some large bullets exceed.
A little more serious (and twice as expensive) is the Acculab VIC123 scale sold by
Sinclair International This is a stripped-down laboratory scale, but is a good notch above the usual shooter's scale. It resolves 0.02 grains instead of the usual 0.1 grains. It has 1850 grain (120 gram) capacity. Unlike the CED Pocket Scale, it is not intended to be portable, and indeed they recommend leaving it plugged in 24/7 so the load cell doesn't have to re-stabilize. I own both these scales and have been quite satisfied with them.
