I also hate die setup/tweaking and will spend money to avoid it as much as possible.
I have a Redding T7 that is use in much the same way; I have misc stuff on it: bullet puller, universal decapper, and then sizing and seating for larger rifle calibers that I do in low quantity.
I know there is some flex in it based on the stroke when sizing a 308 or 6.5 creed: If I run the handle with no case present, the shell holder definitely touches the bottom of the die and there is some cam-over felt.
Actually sizing a case, when it is run all the way to the end of the handle travel, if I put a powerful light behind the shell holder, I can see a very small sliver of light, probably no more than a couple thou, but its there.
How much does this impact consistency of my sizing, I don't know, as I don't have any similar or single stage press to compare it to.
Personally, for me to spend $1200 on an Area 419 press, I'd have to 1) be convinced it would actually be putting out more consistent brass than my Redding, and 2) that difference would lead to a difference in my shooting.
Maybe it would, I don't know, (never looked into it) but I do know for sure a T7 is a whole lot cheaper.
