Hello all. I have a Lee Single stage press and have been using it for about a year now. I bought it used. Not sure of the model but it doesn't put primers in, not a breech lock, just a press. I like it, works great. My question is my dad offered to sell me his old rock chucker. I know it is obviously a heavier press, but will it be that much better than what i have? also what is a fair price for both if i wanted to sell mine? Thanks SB
