I think for a lot of guys using an arbor press and a Wilson seater to seat bullets is a great idea. Even without the force packs, the greatly enhanced "feel" is a huge upgrade over what most guys are cranking on when seating bullets.
Many of the presses out there have handles/arms that are just ridiculous overkill when you consider how much force one actually needs or is really involved when reloading IMO. I went from a Redding Big Boss (WAY too much leverage to feel anything) to a Forster Co-Ax (not much better, I don't like them at all) to a little cheap Lyman Ideal press. The little guy makes much better ammo than the others for whatever reason, and I think a big part of it is that it allows me to feel what's really going on when the others were vague and muted feeling by comparison. I originally only bought it just for seating because I figured it'd be too small for everything, but since getting it, it's more than fine for sizing and everything else, it just happens to shine when seating bullets.
It also shouldn't be understated how huge the effect is of having that heightened sense of "feel" as far as forcing one to be honest with one's self about cleaning up some of the processes earlier upstream. Once I could really feel what was going on at seating, it made me get better at every other step before, no more cutting corners: when I'd skip a step I could feel at seating that I had already fucked something up even before heading off to the range.
I don't do it all the time, but like a lot of guys, if I put the finished rounds in a few separate boxes by seating force ("softer than average", "average", "harder than average") it pretty much guarantees seeing single digit SD's and getting bugholes as long as I didn't screw up anything else earlier in the process.
Using my little press and Forster Ultra Benchrest seater (captures the whole case, to my knowledge as similar to a Wilson in-line seater as can be), I haven't felt the need to go to an arbor press or Wilson seater just yet, but had I not taken the chance on trying the little press, I know I would've ended up there sooner or later.
