Let's see, 2012 I splurged and bought a Co-Ax, wanted one since I started reloading in 1980. Discovered I still had to use the Rockchucker on some cartridges, and for bullet pulling. I wouldn't consider an FA version of the Co-ax.
2013 I splurged and bought a Chargemaster, got by with a Hornady M beam for many years, still use it. The Autotrickler V3 is interesting, and proven. The RCBS Matchmaster is as yet an unknown, that will have to be out for another year or two. Also picked up a Hornady concentricity tool, works OK, added the neck thickness kit to it this year. Also have a Hornady trimmer I had to acquire because of 1 cartridge I had, short Forster wasn't long enough.
2014 I started acquiring 21st Century neck turning setup, just finished this year in doing that, by adding the lathe trimmer stuff to it. That setup is a good one.
2017 I splurged and picked up the Hornady Case prep trimmer setup. Because I'm lazy and wanted an all in one unit. May not be the fastest cutter head, but it will do. Giraud is nice, but, gets pretty expensive with custom add-ons for cartridges, so does the Wilson.
Henderson trimmer is a sweet looking unit, as good a the Giraud? Maybe.
I still use a Redding BR3 powder thrower, thought about a Harrelson a few times.
Still use Lee powder spoons when trickling or using the beam scale.
I've liked Forster style seaters since my first set of Bonanza dies, 40 yrs ago. There are various version of them around now, Redding and RCBS and Whidden and even Hornady. I have mostly Forster, one RCBS and one Hornady seater.
Tempted to try a Redding body die along with the Forster bushing/bumps I have, haven't needed to yet.
I discovered using expander mandrels with using Lyman M-die 2 step expanders with cast bullets, I have them for everything these days, and pulled off all the sizing die expander balls.
Just ordered an Annealeeze unit, can't wrap my head around the price of the Benchsource yet, even though I have around 1000 cases that need doing. Wouldn't be so bad except for the dollar up here at present. Same issue with the Autotrickler V3. But, they didn't exist 5-6 yrs ago, when we had a good dollar.
