The safest and bestest choice is the RCBS ChargeMaster or ChargeMaster Lite.
I agree with this. I've had my Chargemaster 1500 for close to ten years now. Had a little problem with charge weights getting screwy about a year ago as as the warranty has run out bought the Chargemaster Lite. I was screwy right from the start, same problem. did a little research and change out the lighting in the shed where I do my reloading from fluorescent to LED with only minor improvement. Then I read where cell phones and WiFi signals can affect digital scales. I left the cell phone in the house and now both systems are working as they should. Digital scales and smart phones apparently do not get along.
