Trimming is one of those aspects of reloading that I seem to constantly try new tools, never really satisfied long enough to settle in on anything. Here's my trimming evolution since about 2002:
LE Wilson trimmer - simple cheap lathe solution, worked fine when I was only shooting .308WIN and .223REM in small batches
Giraud - now I'm playing with power! Great for volume trimming (trimming 200 cases was easy), it chamfers/deburs in one go too, but changing out cutting heads was a trial-n-error headache until I just spent the money and bought dedicated heads. Sold it when I moved to NZ...thought about buying another but...no.
LCGW World's Finest Trimmer - easy drill-based trimmer with dedicated heads. Set once and forget, but at $70ea it can get expensive if you need to support a bunch of cartridges.
LCGW World's Finest Trimmer 2 - now it's modular so you only need one body and buy cheaper case inserts. But again, changing out can be a bit of trial-n-error getting the distance to the cutting head right each time you swap inserts.
Frankford Arsenal Case Prep Center - got this cheap on a whim. Not even close to comparable with Giraud, but still a handy all-in-one solution. Still a bit of trial-n-error swapping out inserts and getting the lengths right.
Conclusion:
After all these years, I think the Giraud is still the best from my experience, but only if you also buy dedicated cutting heads for each cartridge and set them once. Then changing them out is really easy and there's no trial-n-error adjusting. But for me that was looking like an $800 solution that I wasn't really wanting to re-invest in. So what do I do instead? I use the Frankford Arsenal setup for all of my non-precision stuff like .223REM and .300BLK, where I do a bunch at once, then long gaps between sessions. For the precision stuff like 6.5 flavors, .300NM, .338LM, and some magnum wildcats, I use dedicated WFT1 heads - set once and leave. Just grab the appropriate head, throw it in a hand drill, trim a bunch of brass. No adjusting and screwing up quality brass. And Little Crow Gunworks will make custom trimmer heads for your wildcats.
