Recently I was at a friend's house, and tried to reload without my trusted Chargemaster. I almost pulled my hair out! As it's been stated: Buy one, and you'll never use anything else.
As a side note, a friend bought the Lyman Digital Powder Measue, and had a very difficult time getting it to feed Ball powders. I've never any problems with the RCBS unit.
