I have the Frankford Arsenal Universal Case Trimmer and Prep System. I love it. The more expensive ones don't do anything that this one can't. The primer pocket cleaner and debur tools are great. They move kinda fast so use little pressure and only hold them for a half second. If you are reloading any military ammo or ammo with crimped primers, I do recommend getting the "Case Prep Expansion Kit" with the primer pocket uniformer/crimp remover. It is like $40. The case trimmer works well but is kinda hard to set a precise trim length when switching between different calibers. Note that it measures from the cartridge shoulder, not the overall length of the case. I still use a the Lyman Universal Trimmer to fine tune my high precision rounds after running them through the Frankford. Also, short cases like 300blk do work in the trimmer, but your fingers are going to get real sore trying to hold the case from slipping. Even if you don't use the case trimming part of the Frankford, it's still worth it for the primer pocket cleaner and deburring tools. Sooo much faster than doing it manually. Frankford Arsenal is a cheaper reloading brand overall, and in some products it matters (their press is a piece of garbage), but when it comes to the Universal Case Trimmer and Prep System, it is just as good as the other brands at half the price.
