I load for out Junior high power team so I process a lot of brass. I bought it used from someone else that used to do the same, so the cost was not too bad.
ON the 1050, in this order I deprime, swage the pp, size and trim, expand the case neck. Yes I am wasting a lot of spots on the machine but this works for me. The most important part of this is that we often get brass that is once fired ball that is mixed in with previously loaded stuff. If I have to inspect for primer crimp or swage separately that takes up a lot of time for me. Its easier to just swage every time and if it needs it great if not, it just passes through.
The only thing that I can complain about is that on the first trimming, the Dillon trimmer leaves a large burr, sometimes. expanding as a separate operation knocks most of the interior burr out and I have loaded cases for short line 2-300, without further deburring to no ill effect. However our 600yd ammo I run through the Giraud to knock off the burr.
cases are then polished and loading is transferred to the 550.
on the 550 I prime, drop powder, seat the bullet and finish with a light crimp with a lee factory crimp die for the short line, and no crimp for the 600.
The slower pace of the 550 allows me to inspect each case for split necks, feel the seating of the primer that it has enough tension, and feel the seating of the bullet that it has enough tension and or missed a split neck. You just don't have that feel on a 1050.
BTW I load my own ammo this way and it shoot very well. I am ranked as a HM in Highpower, and am distinguished. We have several juniors that have legged out and reached master with my ammo, so I don't feel its a hindrance. IN fact the short line is all loaded with sierra 77 "seconds" that were donated and charged with either 24.2 grains of varget or 23.1 of 8208 "which I prefer as it meters better in a Dillon and I believe shoots better and cleaner". Long line is loaded with the same charge of varget and a Berger 82.
Previously before I had the 1050 I used a separate toolhead for the 500 to do case prep. I deprimed, sized/trimmed, and expanded leaving one station open. I still had to handle the cases to inspect for a primer crimp and swage if necessary. The less times I have to handle a case the better, and the 1050 is worth that to me. BTW I still prep my 308 and 3006 stuff on the 550 as I only load for myself in those calibers and batch control the brass so I know if it needs swaging or not.
............... Hoz, I've got the old Dillon 450 that's upgraded to 550 spec.'s If I sent it in for re-build I wonder if they'd return it with removable tool head ?? 
BTW just chkd. Dillon's site and they don't list 550B anymore........... Just the 550C
