I reload with the 550B primarily, and even without a casefeeder(another $220) I churn out bullets almost as fast as I can polish them.
You listed carbide dies, which don't require lube, so I wouldn't worry about that.
I saw you listed a media separator, but no tumbler. A good quality tumbler is a must: I've had half a dozen cheapos break on me over the years.
You can save some cash by getting the Dillon accessory package deal: it comes with either "electronic or balance Beam scale, dial caliper, primer flip tray, 2 bench wrenches, 8oz bottle of case lube, safety glasses, machine cover and Lyman Reloading book.
F73-21430 for 650 w/ the balance beam scale ($194.95)
F73-22118 for the 650 kit with digital scale ($259.95)
The aluminum Roller Handle is a lot nicer on your wrist as well (f73-22052) My dad stole mine to use on his RCBS Piggyback(but I got it back when he went hunting without me
