My thoughts were very much like yours. I loaded on a single stage for many many years. I finally a few years ago bought a Hornady LocNLoad. I pretty much leave it set up for 45.
I use the singles stage for everything else but planned to use it mostly for rifle which I don't need to load much for.
I have since bought other parts to load other calibers but generally the progressive is ready for 45 most any time.
I researched the Dillon and they are a good press and they have good customer service and a great little catalog from time to time. I liked some of the features of the Hornady better and they were on sale so I went that route.
It rotates half a position on each handle movement rather than a full which is kind of nice. Being able to remove a case at any station anytime is a real plus. I don't recall now if that's possible on the blues, but I suspect it is.
I think you'd be happy with either.
My single stage is an RCBS Rock Chucker, tough do anything press.
