there's also this one in roughly the same price range (w/my discount)
fyi.. I'd be looking to mainly reload 30-06 for my Garand.
Two things might differ, didn't look too far into the anniversary one.
1) Do they use the same bushings? (Breechlock)
2) slight different peripheral items?
It's the SAME press in both. The Challenger is the cheaper version of that design I think. The "cast" is cast iron and the Challenger is aluminum. Not sure what other material or design elements differ that would impact long term durability.
The press itself was like $75 on Amazon when I looked in December. So the rest of the kit is what you get for the rest of the price, plus you need dies and then all the consumables.
