I have been doing a ton of research on different powder devices. I know that the new RCBS unit came out and it is less than the V3, but less accurate. I have been told by some people that the V3 requires a lot of additional components to work properly. I am wondering how many people have the stock V3. Of those people, do you wish you could upgrade something on it? Those of you that did do an upgrade--did it really make much of a difference.
