Yeah, I use it because I saw this:

and about pissed myself.
$5 trimmer and an old power screwdriver in a hobby vice I already had versus a $200 power trimmer to do EXACTLY the same job= a lot of "Depends" Undergarmets
Sorry to offend anybody's sensibilities, but I just gotta ask... Why spend so much for something that does the SAME EXACT THING? This is a serious question and not meant to rangle or offend.
Well I have the hand powered version of the one you posted, as you can see in the picture. I also have the motorized RCBS unit, as well as two others. They each have a use.
When I process cases I generally will do 500 or more at a time. The motorized job gets it done quickly and accurately enough for my hunting loads and general shooting. If i am looking for extreme precision I use the Forster or Wilson depending on which caliber, rifle or process I am working with.
No biggie on what you, or anyone else uses, it is your personal choices, needs, and budget, and desire that determine what you use, and the level you need it to perform to. If your only looking for ammo to shoot holes in paper, and drop a deer out to 2-300yds, and only shoot a hundred or two rounds a year, simple is great. Heck once upon a time, if cases got too long, too dirty, or had more than 5 or 6 loads on them, I simply chunked them. Trim, clean, count load, naaaa too much trouble. Then you get a new rifle that has a custom chamber in it, and you find you have to upgrade in order to trim the necks not only on the ends but the sides as well. Or your shooting several hundred rounds a month, or you get into competition and want to squeak out the utmost accuracy of your total package. There are many circumstances or situations in which either end of the spectrum works for one person and not another. Just like driving a car verses a truck. I could easily get by driving a car if all I did was go to work and general around town stuff. However having two places in the country to look after, I need a ruck to haul stuff, pull the trailer, and sometimes just to get around up there.
Nowadays I have LOTS of cases, in several calibers, that have over 15 loads through them. All have had their necks trimmed, some reamed, some the outside trimmed, some the bases squared, and some all of the above. So like I said depending on the need of the total outcome of what your looking for, a trim die and file could get you through a lifetime of loading.
I think your stuff is set up nicely for what your accomplishing. Like I said though, once your needs outgrow your system, in one or more ways, you will eventually add to or modify what you have, in one or more ways.
