Lee Challenger Breech Lock Single Stage Press Anniversary Kit - MidwayUSA or Lee Challenger Breech Lock Single Stage Press Kit - MidwayUSA So far as I can tell the only difference in the two is the "anniversary" kit comes with the "safety prime" while the other comes with the "autoprime". The anniversary kit is over $10 cheaper. Any opinions on which is better? I know there are better options out there but not for $100. The money I save I can put towards components. Then later on down the road I may purchase something better, or I may find the simple Lee stuff to work just fine for my needs.
