My 2 cents:
Whatever scale you get, digital or beam, get a quality weight set to be sure that accuracy is really there. I had one scale (an old RCBS beam) that was reproducible, zero'ed in really nice and lied like a cheap rug.
Always check the scale accuracy before you load the first round and pull the trigger. I have seen ugly results caused by skipping that very important safety check. A powder scale weight set runs from $20 to $50, depending on the range of weights. A lot cheaper than replacing a cylinder, or the firearm or having some else open your ketchup bottle.
