I would only use that option as a last resort myself as well.
I have done my share of single feeding primers and still do it with certain topics, but only for ammo where it is being done the hard way during load development. After that work is done, I would be just as likely to run brass on the Dillon as anything else.
I still love my Sinclair and PMA tools, but those are for bench loading during development. These require dexterity and single loading, so I don't think folks with joint pain would want to run them.
I even have some of those Lee APP set-ups that I feed from a Dillon case feeder to bulk deprime and I am still experimenting with one that primes. I think it will work, but I haven't had the occasion to try a big batch with it yet. It is completely hands free and if it works out I will use it to avoid priming on the Dillon with certain jobs.
It isn't expensive unless you also don't already have extra case feeders around, then the cost of one of those Dillon case feeders is a bigger factor than the Lee tool. If you do have a case feeder, then add that Lee APP to the list. They are a little fiddly and fussy to perfect, but when that is solved they do work very fast and easy on the hands. I would recommend these more often, but they do require the user to have a knack for perfecting them with fiddly little adjustments on plastic parts....
My poor girls will have a mess on their hands when I kick off. I have accumulated so many different priming tools over a lifetime of this that I can hardly name one I don't have....
