For the dies, I suggest rcbs or any one you have on hand. The dillon dies are nice, but pricey. Instead of another powder drop, crack off and but tool heads for each caliber you're going to reload for. it's more up front, but so much easier once you're up and running.
IF you were going to use different load data / powder measurements, invest in a few unique tech units.

Unfortunately like guns, reloading is always a work in progress.
