I am split 50-50 between Lee and RCBS with a few hornady thrown in. I have had good experiences with all three companies. RCBS is based in Lewiston ID, While Lee is in Wisconsin somewhere. Now I used to pick up die sets at garage sales for little or nothing. It seems that the wester you go the more used RCBS you see, while easter you go ...the reverse occurs. You can pick up dies cheap on e-bay if you know what you specifically want.
