A decade or so ago I had a Hornady Pro-Jector. It was a good press, but the primer feed and changeover from large/small was somewhat of a pain as well as dies changes.

Everyone said 'get a Dillon' so I tried a few that belonged to friends. I didn't see any particular inprovements over the ProJector in those areas so I held off. When the Hornady L-N-L AP came out, the later ones that had the plastic primer part replaced that kept breaking, that seemed to be the ticket. Never looked back and have 2 of them now.

The Dillon 650 looks comparable, but it is still very time consuming for primer and caliber changeover compared to the L-N-L AP. That is an area that swayed me away from them and an area that needs to be fixed. Dillon makes a good quality, durable press, and backs it up, but they seem just a bit old-fashioned, and not in a good way, compared to what has entered the market lately. Make a more efficient primer feed/changeover system, or even better a universal system, and some means to change the dies easier and they are competitive again.

As far as the SDB goes, it was a good press in it's day, but I can't see where it has any advantage over the Lee Classic Turret today. Especially since the latter handles rifle cartridges easily and it can be both bought and operated more inexpensively.
