I bought a 650 and case feeder last Christmas. Added the bulletfeeder as soon as I got comfortable with the press. I also reload 9mm only for Production. Can't see having the press without the feeders...
You'll want the case feeder and then a bullet feeder. As posted, might as well run a 550. Which a great machine BTW. As much automation as possible.

Oh yes! It works without issue once you get it oriented so your bullets flip properly before dropping. Pretty idiot proof as my (lack of) experience proves....
I've loaded give or take 28,500 rounds of 9mm in the past 12 months. Can't really imagine loading any volume without the feeders.
